Abstract

The invention relates to the field of power simulation, and discloses a steady-state and transient-state offline simulation method and device for a flexible direct-current power distribution network. The method comprises the following steps: establishing a corresponding equipment offline simulation model through action characteristics of main equipment of a target flexible power distribution network, and establishing an offline steady-state simulation model and an offline transient simulation model based on the simulation model and change characteristic curves of the target flexible power distribution network under steady-state operation conditions and transient operation conditions; according to the established simulation model, setting a corresponding off-line steady state simulation plug-in and an off-line transient state simulation plug-in, and connecting the obtained plug-ins with a preset function plug-in by using the same backplane switch so as to obtain a flexible DC power distribution network steady state and transient state off-line simulation device; the off-line steady state simulation plug-in and the off-line transient state simulation plug-in can simulate transient state and steady state operation conditions of the target flexible power distribution network, and operation and maintenance personnel can perform fault drilling and operation training through the simulation device.

Description

technical field [0001] The invention relates to the technical field of electric power simulation, in particular to a steady-state and transient off-line simulation method and device for a flexible DC distribution network. Background technique [0002] Most of the existing DC distribution network simulation systems are DC flow model test devices and digital-analog hybrid DC transmission simulation devices. The simulation device mainly adopts RTDS or RTLAB system. The system hardware structure is too complex and the cost is relatively high. It is mainly used to study the operation characteristics of DC power transmission and distribution, and cannot meet the needs of operation and maintenance personnel in fault drills and operation training. Contents of the invention [0003] The present invention provides a flexible DC distribution network steady-state and transient off-line simulation method and device, which solves the technical problem that the existing DC distribution n...
