Description

technical field [0001] The invention relates to the technical field of power system simulation, in particular to a system for joint simulation of operation and safety monitoring of a large-scale AC and DC power system. Background technique [0002] With the development of national power grid interconnection and the construction of UHV power grid, various types of controllers included in the power system (such as high-voltage direct current transmission, static var compensator, controllable series compensation, generator excitation and speed control, etc.) ) makes the dynamic characteristics of the system more and more complex; the commercial operation of the power system and the shortage of power make the power transmission system run in an extreme mode during peak hours, and the stability margin of the system decreases. Facing the unprecedentedly large and complex power grid, continuing to use the traditional SCADA / EMS system (dispatch automation system) to monitor, control...

AI Technical Summary

Problems solved by technology

However, the simulation device can only realize partial operation simulation of large-scale AC and DC power systems, that is, the operation simulation of the power grid, and cannot realize the simulation of power market, dispatch automation, wide-area measurement and other systems, so it cannot simulate the online dynamics of the power system.
