Description

technical field

[0001] The invention relates to the field of power system analysis, in particular to a full physical model simulation method for a power system. Background technique

[0002] PSS / E is a power system simulation analysis software commonly used in dispatching and operation departments. The typical mode of using PSS / E for power flow analysis is to perform interactive operations based on the man-machine interface provided by the software. First, use the component library provided by the software to manually build the power grid equipment model, and then perform equipment operations based on the component library list to perform single-step power flow calculation. This application mode has problems such as heavy model maintenance workload and insufficient scalability, mainly in the following aspects: ①Manual modeling workload is heavy and maintenance costs are high. In order to reduce the modeling workload, a topology model that does not include switches and switc...
