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. Comprehensive research and testing of new safety monitoring methods such as safety assessment, early warning and decision support system

Abstract

The invention provides an electric power system operation and safety monitoring system. With the system adopted, electric power system safe operation simulation research under an electric power market environment can be carried out; experimental research and software testing of large-scale interconnected power grid safety and stability monitoring technologies can be carried out, such as dynamic safety analysis and assessment of extra / ultra-high-voltage large power grids, WAMS-based electric power system dynamic adjustment and control technologies, and dynamic safety analysis and assessment under the electric power market environment; and analysis and stability assessment can be performed on various kinds of typical operation modes of power grids, and hidden risks can be found as early as possible, and the safe and stable operation of the power grids can be ensured; and power grid accident replay and cause investigation can be carried out, and countermeasures can be researched based on dynamic safety assessment and early warning technologies.

Description

technical field [0001] The invention relates to the technical field of power system simulation, and more specifically, to a power system operation and safety monitoring simulation 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 and dispatch management of the...
