Abstract

The invention relates to an implementation method for an electromagnetic transient multi-time scale real-time simulation interface. The method comprises the following steps that a simulation system is divided into multiple sub-networks connected through decoupling element transmission lines according to the electromagnetic transient multi-time scales, and the time scales of the sub-networks are determined; a decoupling element is decomposed into two controlled sources with the fixed internal resistance through a Thevenin equivalent circuit, the controlled sources are incorporated into the sub-networks, and network matrix initialization is conducted; simulating calculation is conducted, and data of an FPGA platform is received; the data of the FPGA platform is preprocessed to obtain an intermediate variable, and then simulating calculation continues being conducted.

Description

technical field [0001] The invention relates to a realization method, in particular to a realization method suitable for an electromagnetic transient multi-time scale real-time simulation interface. Background technique [0002] In the power system, in order to verify the function and performance of new power automation equipment, a large number of tests are required before the equipment is put into actual system operation. The power system real-time digital simulation system can simulate various operating conditions of the power system in real time. It has the advantages of small size, low power consumption, good versatility, strong repeatability, and lower price than dynamic simulation and digital-analog hybrid simulation devices. It has been widely used in the test of power automation equipment. [0003] The small-step simulation system is an important part of a complete electromagnetic transient simulation system. As the simulation step size becomes smaller, the simula...
