Problems solved by technology
[0003] When using conventional methods to test the control performance of the AGC controller of the wind farm, the control instructions of the AGC controller are changed manually, and then the AGC control instructions are issued manually. In this way, the performance of the AGC controller cannot be accurately detected, and it is impossible to know whether the AGC can respond well to the power command issued by the grid dispatcher when the active power output command is issued by the grid dispatcher, let alone Test the control performance of AGC under static and dynamic conditions

The present invention provides a method and device for detecting the performance of an AGC controller. The AGC controller is connected with a host computer and a plurality of wind turbines. The detection method includes: recording the command reception time when the AGC controller receives a power command from the host computer t1; Obtain the three-phase current value and three-phase voltage value generated by the wind turbine in response to the power control command; calculate and record the active power value P2 according to the three-phase voltage value and three-phase current value, and use the slider effective value algorithm to calculate the effective value of the current slider value; record the response time t2 when the active output of the wind turbine reaches a steady state; calculate the overall response time T1 of the AGC controller based on the response time t2 and command receiving time t1; calculate the AGC controller based on the active power value P2 and the initial power value P1 The control accuracy CA; according to the overall response time T1 and control accuracy CA to detect whether the AGC controller meets the performance index requirements.
Description
technical field [0001] The present invention relates to wind farm equipment detection technology, in particular to an AGC controller performance detection method and device. Background technique [0002] With the continuous acceleration of human pursuit of clean energy, wind power has been more extensively developed. Wind farms transmit power in the form of clustered wind turbines, and their proportion in the power structure of the power system has also increased significantly. The impact of the system is also becoming more and more obvious. In order to better accommodate wind power in wind farms, most wind farms have installed automatic active power control systems (AGC, Automatic Power Control) to realize automatic control of wind farm active power, and increase regional wind power through global control. consumption level. [0003] When using conventional methods to test the control performance of the AGC controller of the wind farm, the control instructions of the AGC ...
