A portable power system digital simulator

Abstract

The invention provides a portable electric system digital simulation instrument which comprises a shell, a control panel, an electro-magnetic transient simulation system, an electromechanical transient simulation system, an SCADA / EMS interface, physical device interfaces and custom interfaces. The control panel, the electro-magnetic transient simulation system, the electromechanical transient simulation system, the SCADA / EMS interface, the physical device interfaces and the custom interfaces are arranged in the shell. The control panel is used for inputting simulation data and issuing control commands. The electro-magnetic transient simulation system is used for receiving electro-magnetic transient network data input through the control panel and responding to the control commands issued by the control panel to calculate the electro-magnetic transient process. The electromechanical transient simulation system is used for receiving electromechanical transient network data input through the control panel and responding to the control commands issued by the control panel to calculate the electromechanical transient process. A plurality of rectangular concave portions with outward openings are arranged on the shell, interface devices used for storing and fixing the interfaces are arranged in the rectangular concave portions in a sliding mode, and the interfaces are electrically connected with components inside the simulation instrument through wires. The portable electric system digital simulation instrument is easy to carry and strong in processing capacity, and can test the performance, the index, the failure and other conditions of a tested object fast and accurately.

Description

technical field [0001] The invention relates to a digital simulator, in particular to a portable power system digital simulator. Background technique [0002] In October 2007, the China Southern Power Grid Simulation Laboratory began to design and develop a real-time simulation platform for AC and DC power systems of China Southern Power Grid (110kV and above), which is referred to as SMRT (Super Mixed Real-Time). The real-time simulation platform connects the real-time simulation of electromagnetic transient state based on RTDS and the real-time simulation of electromechanical transient state based on parallel digital computer through the designed interface equipment. It meets the needs of DC and AC system controllers and protections of China Southern Power Grid, testing and parameter setting of various automation equipment, planning of various operating modes and safety countermeasures, reappearance of various faults and abnormal operating modes, and countermeasure researc...

Problems solved by technology

[0003] For some protective devices, debugging and setting are required at all stages of development, trial operation and operation. However, general tests need to be carried out in laboratories or digital real-time simulation studios. This is an investment in the construction of laboratories. The cost is relatively high, and the second is that it is impossible to realize the on-site test of the equipment, which has great limitations
