technical field

The utility model relates to the technical field of wind power plants, in particular to a monitoring device for wind power plants, which belongs to the technical field of wind power generation monitoring.

Background technique

In recent years, with the promulgation and implementation of my country's "Renewable Energy Law", wind power construction has entered a stage of rapid development, and a large number of wind turbines have been connected to the grid one after another. The total installed capacity of Dagangzi Wind Farm is 240MW, with a total of 160 FD77B/1.5MW wind turbines installed, and the wind field range exceeds 100km ² . Although multiple sets of remote monitoring systems have been built, the data among wind farms, substations, and anemometer towers has not been shared, and each functional module works independently. With the continuous improvement of system operation requirements, the early remote monitoring system of wind farms has been unable to meet the operation requirements of the power grid. The fluctuation and uncontrollability of wind power output make the centralized construction of large-scale wind farms and their connection to the grid inevitably have a negative impact on the safe and stable operation of the power system and the quality of power energy. As a remote monitoring system for wind farms and substations, there is no organic connection , which brings many problems to the dispatching operation of the power grid.

Wind farms are mostly built in remote areas, and there are relatively few mature and experienced operation and maintenance personnel. Although the configuration of single-function and single-phase wind farm monitoring has been realized, many monitoring systems work relatively independently, and the way to deal with the active power dispatching of wind farms is still in the simple startup and shutdown stage, and reactive power compensation is adopted in wind farms. The long-term automatic operation mode of the substation end has not yet been uniformly connected to the voltage and reactive power adjustment system, and its adjustment function cannot be fully utilized to achieve effective information sharing. At the same time, labor intensity and investment waste are increased. Therefore, it is necessary to upgrade and transform the monitoring system of the existing wind farm according to the current situation, so as to realize real-time monitoring of the wind farm.

In order to solve the above technical problems, the utility model provides a wind farm monitoring device, which is controlled by a monitoring and dispatching master station and communicated by a wind farm integrated communication management terminal, which improves the performance of automatic monitoring of wind farms.

Provide a data base.
