Description

Technical field

[0001] The invention relates to an efficient and successful frequency-related network equivalent passivity correction method, which belongs to the technical field of power system dispatching automation and power grid simulation. Background technique

[0002] Power system simulation is one of the important methods to study the transient characteristics of power system. According to different dynamic processes under investigation, power system simulation can be divided into electromagnetic transient simulation, electromechanical transient simulation, and mid- and long-term dynamic simulation. Among them, electromagnetic transient simulation has the highest accuracy, which is mainly used to study the microsecond transient process of power system network components, such as lightning process, wave process and DC commutation failure process. However, high precision comes at the cost of a large amount of calculation. Due to the large amount of calculation, electromagne...
