DC field layer simulation system, digital real-time emulation system and closed loop test system

Abstract

The invention relates to a DC field layer simulation system, a digital real-time emulation system and a closed loop test system. The DC field layer simulation system comprises a field equipment model, a test and control device model, a communication model and a bus communication card and a collection card reading and writing module, wherein the field equipment model is used for simulating an AC / DC switch field, an AC / DC wave filter, a convertor transformer, an SER sequence event and an auxiliary signal in the field, the test and control device model can deliver operation commands, return the field equipment state and collect the analog variable, and the communication model is provided with a data collection card and a field bus communication card. The DC field layer simulation system simulates primary equipment and test and control devices in the field directly through the field equipment model and the test and control device model, reduces the building of the field physical test equipment environment, and can freely select devices to be tested in the simulation range, the problem of control incapability is avoided, the DC field layer simulation system is the system with actual and reliable test environment, and the expansion and the upgrading of the system are convenient.

Description

technical field [0001] The invention relates to a DC field layer simulation system, a digital real-time simulation system and a closed-loop test system. Background technique [0002] RTDS: The full name is Real Tim Digital Simulator (Real Tim Digital Simulator), developed and manufactured by RTDS Company in Manitoba, Canada. It is a device specially designed to study electromagnetic transient phenomena in power systems. [0003] HVDC dynamic simulation test: use digital simulation (RTDS) or physical simulation to establish a power system simulation model, and carry out power system research or control and protection tests. [0004] The main function of the HVDC power station control system is that the system host sends control commands to the measurement and control unit, and the measurement and control unit sends the commands to the field equipment for execution, and returns the status of the field equipment to the system host. It can be seen that the field equipment and m...
