The Analysis of Guangdong Power Grid Stability Control System

In order to maintain the necessary security and stability margin in the operation of power grids and resist all kinds of grid disturbance accidents,according to the regulatory requirements of the State Power Dispatch Communications Center,Guangdong Power Grid Company installs the stability control system in the major substations to form a power grid security defense system.Adopting the method which the theory inferential reasoning and the scene experience unify,this article has introduced the structure and main functions of the Guangdong power grid stability control system,focused on discussing the principle of collecting the value of load could be cut in execution stations and assigning the value of load had to be cut in control sub-stations,and debugged the system in the entire power grid,confirmed the system's reliability and accuracy.There is a positive reference value on debugging and operating the same type regional stability control system.
