Abstract

An upgradable power distribution network digital-analog hybrid simulation system comprises one or more IPM modules. The number of the IPM modules is determined according to the simulation requirement of a power distribution network digital hybrid simulation system. The IPM modules are arranged on the physical side of the power distribution network digital hybrid simulation system. When the number of the IPM modules is multiple, the connection relation between the IPM modules is determined based on the main circuit topology of the physical side of the power distribution network digital hybrid simulation system. The power distribution network digital-analog hybrid simulation system is built and combined by digital and physical subsystems or functional units which are modularly designed and packaged, so that the problem of singleness of a current relatively mainstream special simulation model is solved, and the system can adapt to upgrading and reconstruction requirements caused by changes of factors such as time, space and environment and is beneficial to upgrading and reconstruction of a power distribution network simulation system.

Description

technical field [0001] The invention relates to the technical field of real-time simulation of distribution network, in particular to an upgradable digital-analog hybrid simulation system of distribution network. Background technique [0002] The digital-analog hybrid real-time simulation system is currently the most effective tool for studying the full-condition operation of complex distribution networks including distributed power supplies, high-penetration charging and other equipment. With the rapid development of power electronics and information technology, the traditional distribution network is developing in the direction of AC-DC hybrid, power electronics, and active. Its scale and method make new problems and new demands emerge endlessly, which urgently need to be studied and solved. On the other hand, the digital-analog hybrid real-time simulation system is still a relatively expensive simulation research tool at present. In the early stage of system construction,...
