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...

AI Technical Summary

Problems solved by technology

This application mode has problems such as heavy model maintenance workload and insufficient scalability, which are mainly manifested in: 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 switches is usually established, and it is impossible to carry out detailed simulations on the operation modes such as double bus splitting operation and single-end charging of the line.

②The manual single-step execution mode based on the human-computer interaction interface cannot realize the automatic continuous simulation analysis of the power grid

But it does not involve the PSS / E automatic modeling method based on the full model, and the specific realization of the PSS / E full model power flow calculation
