Automatic power generation control system for wind power plant

Abstract

The invention discloses an automatic power generation control system for a wind power plant. The system comprises a wind power plant data collection module which obtains power data of the wind power plant and transmits the power data to an electric energy distribution module; a grid-connected data acquisition module which is used for acquiring grid-connected side data and transmitting the grid-connected side data to a power control module; a scheduling data exchange module which is used for receiving a power scheduling instruction, transmitting the power scheduling instruction to the power control module and uploading power data of a plurality of fans; the power control module which is used for obtaining active power needing to be output by the wind power plant according to the power scheduling instruction and the grid-connected side data; and the electric energy distribution module which is used for distributing the active power needing to be output by the wind power plant through thepower distribution model to obtain an active power demand of each fan and correspondingly transmitting the active power demand to the fans. By constructing a reasonable data transmission channel, operation and state information of a fan group can be processed and analyzed, the power adjustable fans in the wind power plant can be controlled by combining the grid-connected side data, influence of electric energy fluctuation on the power grid is overcome, and stable regulation and control of a wind power plant unit are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation auxiliary equipment, in particular to an automatic power generation control system for a wind farm. Background technique [0002] With the development of the economy, the demand for electric energy in human society is increasing. As a renewable clean energy, wind energy has been recognized by more and more people. However, the characteristics of wind power output are intermittent and variable. When large-scale wind farms are connected to the grid, they will inevitably face the problem of stable power dispatch. With the expansion of the scale of wind farms, the installed capacity of wind power continues to increase, and the impact of wind farms on the grid gradually appears. Stability and frequency stability issues are highlighted. With the gradual advancement of the country's strategy of establishing a strong power grid, the demand for dispatching and management systems for wind pow...

Problems solved by technology

[0003] Due to the late start of domestic wind power technology, the power regulation system technology of wind farms is immature, especially when the wind speed changes sharply, the impact on the power grid is more obvious, because the existing energy management system often does not consider the impact of power adjustment range on wind turbines , resulting in a huge impact on the unit when the wind speed changes drastically when the energy management system regulates the fan, which intensifies the vibration of the fan and increases the load, thereby shortening the life of the unit
