Embodiment Construction

[0013] The digital dynamic real-time simulation device based on microcomputer is composed of microcomputer, communication card, signal input and output equipment (D / A card, I / O card, A / D card) and power amplifier. Solve the differential equation describing the power system network on the microcomputer, and send the digital signal of the electrical parameter obtained by simulation calculation to the D / A converter and power amplifier in real time through the communication card and I / O card. The amplified signal is directly sent to the relay protection device and controller to be tested for real-time testing of the device. At the same time, the response signals of the tested relay and controller can be fed back to the PC in real time through the A / D converter and I / O card, thus forming a real-time, closed-loop simulation test system, see figure 1 .

Description

technical field [0001] The invention relates to a microcomputer-based power system digital dynamic real-time simulation device, which belongs to the power system simulation device, and particularly relates to power system simulation research and equipment testing. Background technique [0002] Power system real-time simulation is mainly used in real-time testing of control and protection devices, with the purpose of verifying whether the performance of the devices meets the design requirements before they are installed and put into operation. Real-time simulation is divided into physical analog simulator (dynamic model) and real-time digital simulator based on digital signal processor (DSP for short). [0003] The physical simulation simulator is a dynamic simulation experiment, which uses scaled-down actual physical equipment to simulate the actual power system, and then connects the protection device and controller to the simulated system for testing. It is a pure simulati...
