Wind Power Network News: Wind resources are renewable energy sources that have commercial and large-scale development conditions and are inexhaustible. We can build wind farms in areas with good development conditions, and use wind farms to convert wind energy into convenient electrical energy. The construction of wind farms can reduce the consumption of fossil resources, reduce the pollution of the environment caused by the emission of harmful gases such as coal burning, and at the same time play a positive role in promoting the rapid development of the local economy.
Most of the electric energy converted by wind farms cannot directly enter thousands of households, but needs to be connected to the power system, and then enters thousands of households through the power system.
Not long ago, the “Hong Kong-Zhuhai-Macao Bridge” was officially opened to traffic, which connects Hong Kong, Zhuhai and Macau. Isn’t the access system a “bridge”? It is connected to the wind farm at one end and thousands of households at the other end. So how to build this “bridge”?
One|Collect information
1
Information provided by wind farm construction unit
The feasibility study report and review opinions of the wind farm, the approval documents of the National Development and Reform Commission, the wind farm stability report and review opinions, the wind farm reactive power report and review opinions, the government approved land use documents, etc.
2
Information provided by the power supply company
The current status of the power system in the area where the project is located, the geographic wiring diagram of the grid, the access of new energy around the project, the situation of the substations around the project, the operation mode, the maximum and minimum load and load forecast, the configuration of reactive power compensation devices, etc.
Two|Reference Regulations
The feasibility study report of the wind farm, the technical regulations for access to the power system, the technical regulations for grid connection, the principle of reactive power compensation configuration, the safety and stability guidelines, the technical guidelines for voltage and reactive power, etc.
Three|Main content
The access of wind farms is mainly the construction of “bridges”. Excluding the construction of wind farms and power systems. According to the forecast of power market demand and related grid construction planning in the region, through analysis and comparison of regional power supply area load curves, related substation load curves and wind farm output characteristics, power balance calculations are carried out to determine the consumption of wind farms in regional power supply areas and related substations At the same time, determine the power transmission direction of the wind farm; discuss the role and position of the wind farm in the system; study the wind farm connection system plan; put forward the wind farm electrical main wiring recommendations and the selection requirements of related electrical equipment parameters.
