AGC/AVC Dual Redundancy
Wind and photovoltaic power generation differ from conventional power sources in their operating principles. When frequency and voltage fluctuations occur in the power grid, these new energy sources lack rotational inertia to provide support, thereby reducing the grid’s transient stability. To ensure that the integration of new-energy power plants does not compromise grid stability and to standardize the configuration of AGC/AVC substation control systems for grid-connected power plants, as well as clarify the requirements for AGC/AVC integration, the power dispatch center has mandated that wind farms and photovoltaic power stations within the grid must implement a dual-redundancy design for their AGC/AVC substation control equipment. Furthermore, power generation from new-energy plants must also actively participate in maintaining grid voltage stability.
The power plant is equipped with an AGC/AVC control system, each set of which includes two intelligent power control units (hereinafter referred to as AGC/AVC substations) and switches, among other equipment, to implement dual-redundancy control for the plant’s AGC/AVC functions. The network topology diagram is shown below.
