Typical design for the master station function of security and stability control system for power grid

The power grid security and stability control system is the second line of defense to ensure the safety and stable operation of the power system, and the master station in stability control system is the decision-making unit. At present, there is no unified standard principle for the master station function of the stability control system, which has brought great trouble to the standardized design of the stability control device. Based on the status quo of the master station function configuration of the stability control system, this paper defines the principle of the master station function configuration, and focuses on the typical design schemes of power grid operation mode identification, fault strategy table, generator shedding function and load shedding function, It can guide the construction of stability control systems in different regions of China better and better in the future.
