TianJin West Railway Station Roof Solar Power Green Energy Services Surrounding

Reporters learned from relevant departments, has been organized by the City Development and Reform Commission and other multi-sectoral assessment of Tianjin West Railway Station solar photovoltaic power generation project, has now entered the commissioning phase, will soon put into used, the system in Tianjin West Railway Station platform stuff on 36,000 square meters of ceiling the laying of solar panels, green energy will be provided to West station area and the surrounding residents.

It is reported that is also the city first 10 kV-megawatt solar photovoltaic power station. Solar photovoltaic power generation system is divided into off grid solar system and on grid solar system operation in two ways. There are areas in the public power grid, photovoltaic power generation system connected grid operation, eliminating the need for off grid solar power system must be part of the battery, not only greatly reduce the cost, but also higher power generation efficiency and better environmental performance . This formal grid Tianjin West Railway Station to connect grid using operates.


It is assumed that the power project feasibility study and design of the Third Railway Survey and Design Institute experts, the project is for building integrated solar photovoltaic power generation system, photovoltaic tile on the platform canopy, angle and canopy consistent components, the total area reached 36 thousand Project construction scale is about 1.9 MW, including glass, amorphous silicon component design installed capacity are about 1.3 MW, flexible amorphous silicon component design installed capacity are about 0.6 MW. The project is the first 10 thousand megawatts solar photovoltaic power station in Tianjin City, also promote the development and utilization of new energy city landmark project. The project combined with the construction of a building of TianJin West Railway Station, all project components are laying in the West that the platform canopy top, equipment room set basement in the railway station. After the commissioning of the equipment, not only can provide power for the station itself, even through the grid to provide residual power for other places.

Shigatse Tibet Solar Photovoltaic Power Station Grid Operation

Shigatse, Tibet solar photovoltaic power station the first-stage project completion and incorporated into Tibet power grid operation. Xinhua News Agency reporters Tao Wen taken July 5th, several workers are in the Shigatse, Tibet solar PV array construction. On the same day, Tibet Shigatse solar photovoltaic power plant the first-stage project completion and incorporated into Tibet power grid operation.

On the same day, Tibet Shigatse solar photovoltaic power plant the first-stage project completion and incorporated into Tibet power grid operation. An annual generation capacity of the solar power plant are about 2023 million kilowatts, which can meet the Shigatse City 10 million farmers and herdsmen electricity demand, not only greatly improved Tibet the shortage of power supply, voltage instability situation , each year also to save standard coal 9000 tons, to reduce emissions of greenhouse gas carbon dioxide are about 17820 tons, is the current Tibet grid to run the largest solar photovoltaic power station.

The Characteristics Of Home Distributed Solar Power Plant

Distributed home solar power plant usually refers to the use of distributed resources, installed a smaller scale and arranged power system in their own home, it generally access below 35 kV or lower voltage level of power grid. Distributed solar photovoltaic power station refers to the use of photovoltaic modules, the direct conversion of solar energy into electrical energy distributed photovoltaic power system. Understanding distributed home solar power plant characteristics are more helpful for us to its overall control.

The characteristics of home distributed solar power plant:
　　
1. Output power is relatively small. The traditional centralized power plants frequently several hundreds of thousands kilowatts, or even millions kilowatts, large-scale application improve the economic. The modular design of solar off grid system photovoltaic power generation determines the the scale can be big or small, according to the capacity of the venue for adjusting the photovoltaic system. Generally, the capacity of a distributed solar photovoltaic power plant project is within thousands kilowatts. Unlike centralized solar power plants, the size of the photovoltaic power station has very little effect on the efficiency of electric power generation, so the economic effect is also very small, the rate of return on investment of small solar PV systems are no than lower the larges’.

2. Little pollution, environmental benefits outstanding. Distributed solar photovoltaic power plant project in the power generation process, there is no noise or nor to air and water produce pollution. However, it need to pay attention to harmonious development of distributed solar PV with the surrounding urban environment, in using clean energy, considering the public concern about the beauty of the city environment.

3. To a certain extent, ease the power shortage in the local situation. Distributed solar PV power plant output maximum in the daytime, just at this time the greatest demand for electricity. However, the energy density of distributed solar PV power plant is relatively low, the power per square meter of distributed solar PV power plant system is only about 100 watts, plus the installation of the PV modules for limiting in the roof area of the building, so the distributed solar photovoltaic power plants can not be fundamentally solved the power shortage problem.
