Simulation platform and simulation method for power distribution network loop closing and breaking with phase angle difference

Abstract

The invention relates to a simulation platform and simulation method for power distribution network loop closing and breaking with phase angle difference. The platform comprises a drawing function module and a loop current calculation module; and the drawing function module comprises a drawing interface and an electrical equipment model adding module. with middle and low voltage sides of 220kV transformer models adopted as starting power supply points, on the basis of the actual grid structure of a regional power grid, corresponding electrical equipment models are added to the drawing interface through the electrical equipment model adding module, and and the setting of the parameters and states of all the electrical equipment models and mutual connection of the electrical equipment models are completed according to the actual grid structure of the regional power grid, and finally a power flow simulation diagram with the middle and low voltage sides of all the 220kV transformer models as the starting power supply points is drawn. In the prior art, the power distribution network loop closing and breaking with phase angle difference is manually calculated and analyzed by technicians, as a result, conclusion error is large, an analysis result is simple and the significance to actual operation is not great,and power grid accidents and risks are easy to occur when operation is carried out according to the analysis result. With the platform and method adopted, the above problems can be solved.

Description

technical field [0001] The utility model relates to the field of distribution networks, in particular to a simulation platform and a simulation method for the closure and solution loop of a distribution network with phase angle difference. Background technique [0002] In the regional power grid, there was no simulation platform specially used to simulate the combination and de-loop of the distribution network with phase angle difference. The original phase-angle difference and de-loop of the distribution network were manually calculated and analyzed by technicians. The conclusion error was large, and the analysis result was simple and practical. The operation is of little significance, and operations based on the analysis results are prone to power grid accidents and risks. Contents of the invention [0003] The purpose of the present invention is to provide a simulation platform for the closure and solution loop of the distribution network with phase angle difference, wh...
