The policies are as follows:

1. Strictly implement planning and early warning requirements.

The energy authorities of all provinces (autonomous regions and municipalities) must strictly implement the "Guiding Opinions of the National Energy Administration on the Implementation of the 13th Five-Year Plan for Renewable Energy Development" (Guonengfa Xinneng [2017] No. 31 ) (hereinafter referred to as the "Guiding Opinions"), the annual scale and related requirements of the new wind power construction scale plan in each region. Areas with red and orange warnings should strictly implement the relevant requirements of the "National Energy Administration's Notice on the Release of Wind Power Investment Monitoring and Warning Results in 2018" (Guonengfa Xinneng [2018] No. 23), and must not be used during the "Thirteenth Five-Year Plan" The scale of the plan will be increased during the mid-term evaluation of the plan. If areas with green warnings need to adjust their planning goals, they can apply to the National Energy Administration for planning adjustments and organize implementation based on the mid-term assessment of the 13th Five-Year Plan on the premise of implementing the construction of supporting power grids for wind power projects and ensuring consumption.

2. Make consumption work the first condition.

All provinces (autonomous regions and municipalities directly under the Central Government) must follow the "Notice of the National Development and Reform Commission and the National Energy Administration on Issuing the Implementation Plan for Solving the Problem of Abandoned Water, Wind, Wind and Solar Energy" (Fagai Energy [2017] No. 1942 ) and the "Notice of the General Affairs Department of the National Energy Administration on Submitting and Implementing the Work Plan for Solving the Problem of Abandoned Water, Wind, and Solar Energy" (Guoneng Zongtong Xinneng [2018] No. 36) requires submission to the National Energy Administration in 2018 In the 2016 renewable energy power consumption work plan, provinces (autonomous regions and municipalities directly under the Central Government) that have not submitted the report will stop the implementation of the "Guiding Opinions" on the new wind power construction scale in the region.

3. Strictly implement the conditions for power transmission and consumption.

New wind power projects included in the annual construction plan must be based on the grid company's commitment to invest in the power transmission project and ensure that the minimum guaranteed annual utilization hours are achieved (or the wind curtailment rate does not exceed 5%, the same below) As a prerequisite, projects with local consumption conditions in the city (county) level area where the project is located will be included in the annual construction plan first. For wind power base projects that are transmitted and consumed through inter-provincial and inter-regional power transmission channels, the project transmission and consumption plan and price adjustment mechanism should be agreed upon in the power transmission and reception agreement between the provincial governments at the sending and receiving end and the medium- and long-term power purchase contract of the power grid enterprise. In principle The power grid enterprises of Shangshouduan Province (autonomous regions and municipalities directly under the Central Government) should issue a commitment to accept the transmission of wind power capacity and electricity through channels.

4. Promote competitive allocation of wind power projects.

From the date of issuance of this notice, new centralized onshore wind power projects in provinces (autonomous regions and municipalities directly under the Central Government) that have not yet issued the 2018 wind power construction plan and offshore wind power projects with undetermined investment entities should all be approved. A competitive approach is used to configure and determine feed-in electricity prices. Provinces (autonomous regions, municipalities directly under the Central Government) that have issued wind power construction plans for 2018 and offshore wind power projects that have determined investment entities can continue to advance the original plans in 2018. Starting from 2019, all newly approved centralized onshore wind power projects and offshore wind power projects in each province (autonomous region, municipality directly under the Central Government) shall be allocated and determined through competitive methods. The energy authorities of all provinces (autonomous regions and municipalities directly under the Central Government), together with relevant departments, shall formulate competitive allocation methods for wind power projects with reference to the "Guidance Plan for Competitive Allocation of Wind Power Projects (Trial)" issued with this notice, and send a copy to the National Energy Administration and announce it to the whole society. Accordingly, in accordance with the The annual new construction scale determined in the "Guiding Opinions" organizes the competitive allocation of wind power projects in the region. Distributed wind power projects do not need to participate in competitive allocation and will gradually be included in the scope of market-based transactions for distributed power generation.

5. Optimize the investment environment for wind power construction.

The energy authorities of all provinces (autonomous regions and municipalities directly under the Central Government) must improve land use planning for wind power projects and give priority to unused land for the construction of wind power projects. Sites must not be located within the ecological red line range and other areas where construction is not allowed by the state. , and should avoid the land range where urban land use tax is levied. If it is within the range of cultivated land occupation tax, the collection area and collection standards should be reasonably determined based on the characteristics of the wind power project land and the degree of impact on land use. During the development process of wind power projects, relevant local government departments shall not charge enterprises in disguised form in the name of resource transfer, enterprise assistance and donation, etc., and shall not force the project to directly transfer shares or use the proceeds for various affairs that should be borne by the government. When relevant departments at the city (county) level recommend wind power projects to participate in the competitive allocation of new construction scales, they should make effective commitments or explanations on the above construction conditions. The provincial energy authorities should assess the performance of the commitments by the relevant cities (counties). , and serve as an important basis for subsequent arrangements for the scale of new wind power construction.

6. Actively promote the full consumption of wind power projects nearby.

Support areas rich in wind energy resources to build wind power projects based on the power needs of local large industrial enterprises and industrial parks, and strive to achieve development without subsidies with the support of relevant national policies. Encourage prefecture-level cities with strong power demand to select wind energy resource sites with annual power generation utilization hours of about 3,000 hours. Under the premise that provincial power grid enterprises ensure full consumption nearby, use bidding methods to select investments. Develop enterprises and determine grid-connected electricity prices, especially encouraging affordable grid-connected projects that do not require state subsidies.

The development prospects of China's wind power and other new energy power generation industries are very broad, and it is expected to maintain rapid development for a long time to come. As the country continues to increase its support for the development of clean energy, batches of The settlement of large-scale wind power projects has accelerated the construction of wind power bases.

Types of wind power generation: horizontal axis wind turbine; vertical axis wind turbine; Darrieux type wind wheel; doubly-fed type generator; Magnus effect wind wheel; runoff double wheel effect wind wheel .

Although there are many kinds of wind turbines, they can be summarized into two categories: ① Horizontal axis wind turbines, the rotation axis of the wind wheel is parallel to the wind direction; ② Vertical axis wind turbines, the wind wheel The axis of rotation is perpendicular to the ground or the direction of airflow.

Detection method

1. Monitoring of wind turbine operating status.

2. Information about a single wind turbine, wind turbine rotor, transmission chain, generator, converter, transformer, cabin, yaw system, tower, weather station status monitoring.

3. Wind speed, wind direction, impeller speed, grid frequency, three-phase voltage, three-phase current, generator winding temperature, ambient temperature, cabin temperature, output, etc. are monitored.

4. Ensure the real-time and reliability of wind power plant data. Adjust the optimality of wind energy in real time to achieve green energy from wind power and meet the secondary protection requirements of the national power system.
