Scope

GB/T 40600-2021 is the English-translated version of 风电场功率控制系统调度功能技术要求.

GB/T 40600-2021 sets technical requirements for the dispatching functions of a wind farm power control system, the system that directly controls wind turbines and reactive power compensation devices to perform automatic generation control, primary frequency control and reactive power and voltage control.

It covers basic requirements, configuration and communication information, the scheduling functions of the system, testing of those functions and performance indices.

Informative annexes give the control link, basic collected information, an example droop curve for primary frequency regulation and the calculation of active power, reactive power, voltage and primary frequency control performance indices.

It applies to new or expanded wind farms connected to the grid at 35 kV and above and can be used for system design, development and grid-connection function selection. It was issued on 11 October 2021 and has applied since 1 May 2022.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Wind farm automatic generation control

According to the real-time control commands (or preset target commands) of the power grid and the output characteristics of the wind turbines, the active power of the wind turbines is reasonably allocated to achieve The active power of the wind farm is automatically closed-loop control, so that the active power output of the wind farm can meet the control requirements of the power grid.

3.2 Wind farm primary frequency control

When the frequency of the power system deviates from the specified frequency modulation dead zone, the wind farm quickly and automatically adjusts the active power to respond to the change of the grid frequency and maintain Support the control function of stable grid frequency.

3.3 Wind farm power control system

Through direct control of wind turbines and reactive power compensation devices, automatic power generation control, primary frequency modulation control and reactive voltage of wind farms are realized Control and other functions of the system.
