Wind Power Network News: With the launch of Guoneng Xinneng’s [2017] No. 3 document “Notice of the National Energy Administration on Accelerating the Construction of Distributed Access Wind Power Projects”, distributed wind power projects in various provinces, cities and counties across the country are in full swing In the planning and construction of wind power projects, what are the main limiting factors in the planning and construction of decentralized wind power projects? Xiaobian will take stock of them one by one today.
1. Grid access
Guoneng Xinneng [2017] No. 3 document: “…the access voltage level should be 35 kV and below. If it is connected to a substation with a voltage level of 35 kV and above, it should be connected to a voltage level of 35 kV and below. the low pressure side of the…”
Since the policy requires that the access voltage of distributed wind power projects shall not exceed 35kV, the distance relationship between the construction site of distributed wind power projects and the access point is greatly limited. In principle, the decentralized wind power construction site should be within 15km from the access point, and the farthest should not exceed 18km.
2. Capacity limitation
Guoneng Xinneng [2011] No. 374 document: “…Except for demonstration projects, the total installed capacity of a single project shall not exceed 50,000 kilowatts…”
Guoneng Xinneng [2011] No. 374: “… encourage development enterprises to bundle wind turbines with multiple grid access points located in the same county into one project and agree to carry out preliminary work, handle relevant supporting documents, and conduct project approval and development and construction, the scale of a single bundling project does not exceed 50,000 kilowatts…”
Guoneng Xinneng [2017] No. 3 document: “…the upper limit of wind power capacity connected to a grid access point is premised on not affecting the safe operation of the grid, and the total access capacity of each voltage level is considered as a whole, and multi-point access is encouraged. . It is strictly forbidden to send electricity to voltage levels of 110 kV (66 kV) and above…”
The latest policy “Guoneng Xinneng [2017] No. 3″ does not stipulate the capacity of a single decentralized wind power project, but only requires that the upper limit of wind power capacity connected to a grid access point does not affect the safe operation of the grid. Therefore, the capacity of distributed wind power projects should be considered in an overall manner according to the grid conditions, load characteristics and absorption capacity of the construction site.
3. Resource situation
Considering the power generation and income of the decentralized project, it is believed that the planning and development of the decentralized wind power project can be carried out at the current stage when the wind speed is above 5.0~5.5m/s.
4. Centralized wind power
When selecting sites for decentralized wind power projects, centralized wind power projects that are already in operation, approved for plan, and under planning should be avoided. If it is adjacent to the above projects, the impact of the above projects on the decentralized wind power project should be considered.
V. Land Sensitive Factors
When selecting a site for a decentralized wind power project, it is necessary to avoid patchy sensitive areas such as basic farmland, forest land, minerals, protected areas, and scenic spots, and at the same time, pay attention to avoiding point-shaped sensitive areas such as military, cultural relics, and sites.
