Uncategorized No Comments

 

A company requires its own office premises for a wide range of good practical reasons. The type and dimension of office and also its geographical place are likely to depend on a number of factors including expenses, distance to markets as well as abilities, and availability of properties. The internal design of offices is likely to be broad as well as varied, and also quite pertaining to initial format of the building itself. It is within this context that lots of companies pay a great deal of focus to the primary practical facets of the workplace e.g. energies, phone systems, parking area, lifts, illumination, plumbing etc. as well as much less interest to just how the real layout of the workplace will fit the business itself. Asking why a company requires office partitions increases more inquiries and also vital points which tend to show that there is undoubtedly a fantastic and boosting demand for them in the business world.

Exists a demand for individual offices or dividing the office space?

Commonly the administration feature itself is separated among specific vital personnel, and also these workers will need their very own area/ room/ office too. modern office partitions  Office partitions by their very nature are physical obstacles and divider panels, and as such show up most likely to be needed by many companies.

Office partitions can definitely be solid, taken care of, long lasting as well as long-term structures. They have actually the included advantages nevertheless of being made from one of the most up to date materials which can include colours, textures, surfaces, doors and glazing choices in whatever placement securely satisfies the personalized requirements of the business.

One of one of the most modern as well as preferred sorts of office partitions is glass partitions. These can be used to simply work as visually pleasing divider panels, or they can be total floor to ceiling spaces. These can incorporate a mounted or frameless look, can include film layouts on the glass, and also sturdy glass doors.

It is apparent therefore that all kinds of businesses are most likely to have a need for separating the workspace in some way, and for that reason potentially have a requirement for office partitions.

How to choose PV inverter for household PV power system?

Decor No Comments

The main function of the PV inverter is to turn the DC power from the PV module into AC power, as the inverter is the only device with “wisdom” in the PV system, in addition, the PV inverter also undertakes important functions such as detecting the operating status of the module, grid and cable, communicating with the outside world, and system safety housekeeping. So, what should I pay attention to in the selection of household PV inverter?

c channel profile

1, the configuration of safe and reliable DC switch.

Household power station situation is very complex, the location is also relatively remote, once the components occur short-circuit grounding and other phenomena, after-sales service can not immediately arrive, there may be a fire or electrocution accident, then you can let the owner disconnect the DC switch (this operation is very simple), to avoid further escalation of the fault.

2、Minimize the noise.

Household photovoltaic inverter installed in residential homes, if the noise generated in operation, will bring great inconvenience to people’s lives, the sound of the inverter from the fan and inductor, the inverter to adopt a fanless design, no fan inside and outside, to eliminate the largest source of noise; inductor overall gluing, and put into a separate aluminum-cased case to reduce the current and vibration sound of the inductor.

3. Adopt multiple display modes.

Both LCD display, intuitive and convenient, suitable for some users who do not have smart phones to view, physical buttons have a short life span, voice-activated buttons are simple to operate and have a longer life span; adopt GPRS monitoring, monitor the operation of the power station with smart phones, can be viewed at any time and anywhere, can unify the management of thousands of units or even tens of thousands of power stations, two-way monitoring system can provide proactive services to find problems, fault warning, the problem remote diagnosis and processing functions.

4, high power generation: Inverter affects the power generation of many factors, need to pay attention to.

First is the inverter to be stable, can not be bad, because once the inverter failure to repair the machine or replace, as little as two or three days, as much as five or six days, during which the loss of electricity costs a lot.

The second is the efficiency of the inverter, the three efficiencies of the inverter, maximum efficiency, weighted efficiency and MPPT efficiency, the greatest impact on power generation is the weighted combined efficiency, because the inverter works at less than the rated power is the most time.

Third is the DC operating voltage range, the wider the voltage range, representing the early start and late stop, the longer the power generation time, the higher the power generation capacity.

Fourth, the MPPT tracking technology should have high accuracy and fast dynamic response, which can adapt to rapid changes in light and improve power generation efficiency. Fifth, the inverter output voltage range should also be wide, preferably between 180-270V, but of course not too high, more than 270V will have an impact on household appliances.

National distributed photovoltaic “county-wide promotion” policy will reconfigure the rural grid development model

Business No Comments

With the promotion of new power system construction with new energy as the main body, more and more distributed photovoltaic access to rural power grid. Under the guidance of the national “double carbon” goal, China’s rural distributed photovoltaic power generation will also grow significantly year by year. The large-scale development of distributed photovoltaic power generation in rural areas will definitely bring challenges and far-reaching effects to the traditional rural power grid, and thus reconfigure the rural power grid development model. It is urgent to promote the construction of a new rural grid to meet the “double carbon” goal.

In the future, as the grid will be connected to a large number of distributed photovoltaic and a variety of new energy sources, the rural power distribution system will change from a radial passive network to an active network with a large number of distributed power sources, and the physical characteristics of the grid will change significantly. Therefore, the traditional sense of the rural grid will not be able to adapt to the large-scale intermittent distributed power supply access, the future, rural power grid will also face new challenges.

One is the lack of rural grid capacity. In the local rural grid-based areas, due to the regional load characteristics and photovoltaic, wind power and other power supply characteristics do not match, resulting in the difficulties of consumption, the need for transformation and upgrading or new substation capacity.

Second, the impact of power quality of the grid. As the grid access capacity increases, the voltage deviation will show a “U-shaped” change that decreases and then increases, and in extreme cases even exceeds the upper limit of voltage requirements.

Third, it affects the automation and relay protection action of the distribution network. Traditional rural distribution network generally does not take into account the dual-side or multi-side power supply situation, the configuration of the current protection is mostly non-directional overcurrent protection. After a large number of distributed photovoltaic access, the system failure system and photovoltaic are provided to the fault point short-circuit current, changing the current flowing through the protection, which may lead to relay protection device misoperation, rejection and other acts at the same time, there is a risk of incorrect action of protection such as ready to throw, reclosing, will further expand the scope of grid accidents.

Fourth, the impact of harmonics and hazards. Distributed photovoltaic high proportion of access, due to the inverter and other power electronic components of large-scale access to the grid, coupled with some inverters of poor quality, or will lead to serious harmonic pollution of the grid exceeds the standard. The harm of grid harmonics is multifaceted, will lead to increased grid loss, relay protection false operation, meter measurement inaccuracy and other problems, reducing the reliability of power supply and power quality.

Fifth, the county-level power grid peaking difficulties. The high proportion of intermittent non-peak power sources such as photovoltaic access to county-level rural grids, the grid can be dispatched to the shortage of peaking resources, because the traditional rural grid does not have energy storage equipment, will lead to local areas of photovoltaic power generation peak and peak electricity dislocation, grid peaking difficulties, especially during holidays.

Compared with the traditional rural network, the new rural network should have the access capability to consume a large amount of renewable distributed clean power and ensure the quality of power supply. Therefore, the construction of new agricultural network should be tailored to local conditions, taking into account the stage of rural economic development and distributed photovoltaic characteristics, take different models, not a one-size-fits-all.

First, we should carry out new rural grid planning research, improve the rural distribution network standards, put forward optimization and adjustment program, in the planning lead to achieve distributed photovoltaic orderly construction and access. Comprehensively sort out and improve the relevant system standards for distributed photovoltaic power generation, improve the relevant control processes, and guide the collaborative development of source, network, load and storage. Actively do a good job of PV grid-connected services, PV grid-connected supporting engineering construction, strengthen the upgrading of rural distribution networks to ensure the safe and stable operation of a large number of distributed PV grid-connected.

Second, vigorously cultivate the rural electricity market, local, near the consumption of photovoltaic power generation. To be implemented through rural electrification, electrical energy substitution and other projects to further increase the proportion of electrical energy accounted for rural terminal energy consumption; efforts to promote the electrification of agricultural production and life, and strive to enhance the ability of local consumption of distributed photovoltaic in rural areas; comprehensive expansion of the electrification market in agriculture, and promote the upgrading of agricultural production technology.

Third, we should promote the construction and improvement of policies and regulations to promote the development of new agricultural network (power system). We should assist the government to introduce relevant policies and regulations to guide investors, consumers and grid enterprises to operate in an orderly manner under reasonable prices according to market-oriented rules. Develop the principle that investors need to bear the responsibility of energy storage construction and harmonic elimination, and the supporting energy storage devices and harmonic elimination equipment can be built and managed by the investors themselves, or they can adopt market-based subscriptions, unified construction and shared resources.

The development of distributed photovoltaic has many points of fit with the rural revitalization strategy. The stable income provided by PV can better promote rural development. At the same time, PV has many application scenarios in rural areas, roofs and agricultural sheds can be combined with PV industry, thus changing the rural lifestyle. Through the development of distributed photovoltaic, will significantly improve the level of rural electrification, will also promote the intelligent transformation of rural power grid. In addition, combined with the relatively mature “photovoltaic + agriculture”, the face of the countryside will have a greater improvement. At the same time, the accelerated development of distributed photovoltaic, will also bring greater help to achieve the “double carbon” goal.
