Wind Power Network News: Recently, at the National Decentralized Wind Power Development Forum and Decentralized Wind Farm Design and Equipment Selection Seminar held in Chengdu, Director Shi Jingli of the National Development and Reform Institute for Member Energy The progress of wind power: Many development companies are active, but the degree of advancement is lagging behind expectations; the main problems and difficulties lie in the technical level and the policy and implementation level.
This article sets aside the policy aspect first, and will mainly summarize the technical points that experts have published, discussed and reached consensus.
1. Access
As we all know, decentralized wind power first finds the grid and then finds the wind, so the grid access point must be determined first. The development enterprise should first communicate with the local power grid about the possibility of access, understand the site of the access station and the load in the station, and then evaluate the capacity and feasibility of the access, so as to determine the development capacity.
2. Resources
The scale of decentralized wind power is small, usually only a few wind turbines, and some even one wind turbine, which requires higher accuracy of wind resources; in addition, the development cycle of decentralized wind power is short, and it is particularly important to evaluate wind resources more quickly and accurately. Experts suggest that for plain terrain, wind measurement tower data near the planned site can be used, and for complex terrain, big data, cloud computing, lidar and other forms can be used to evaluate wind resources.
3. Fan
Choose a wind turbine with mature technology and large single-unit capacity. The high tower and long blades of large units can meet the resource conditions of low wind speed areas and can effectively reduce land occupation, which is a key point for the selection of decentralized wind turbines. Of course, the model selection is not blindly large, the final model selected is the combination of the best power level and blade diameter matched to different resource conditions.
Four, operation and maintenance
Unmanned, digital, intelligent, and precise are the operation and maintenance requirements of decentralized wind power proposed by experts and machine manufacturers at this conference. Mingyang Intelligent uses a large number of video surveillance systems, supplemented by Mingyang intelligent operation and maintenance platform, to carry out regional centralized operation and maintenance. Based on the intelligent AI “small cloud” of knowledge warehouse, Shanghai Electric provides cloud storage of product and fault knowledge base, knowledge mining and fault intelligent diagnosis and early warning, and realizes Fengyun intelligent multi-dimensional monitoring.
