Abstract

An embodiment of the invention relates to the field of flexible direct current transmission emulation techniques, and discloses an emulation platform of an MMC system based on an FPGA. The emulation platform includes: a personal computer (PC), a CPU emulator, an FPGA emulator and an external control or protection device of an MMC system. The PC, the CPU emulator and the FPGA emulator are connectedin turn. The FPGA emulator is also connected communicatively to the external control or protection device. The PC is used for constructing a system emulation model of the MMC system and for transferring the system emulation model to the CPU emulator and the FPGA emulator respectively. The system emulation model includes all the primary equipment emulation models, converter valve emulation modelsand pole control or station control emulation models of at least two converter stations of the MMC system. The PC is also used for controlling the CPU emulator to run the pole control or station control emulation models, and for controlling the FPGA emulator to run all the equipment emulation models and the converter valve simulation models in real time to implement hardware-in-the-loop testing ofthe external control or protection device. The emulation platform of the invention can realize real-time emulation and hardware-in-the-loop testing of traveling wave protection.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of flexible direct current transmission simulation technology, in particular to a simulation platform of an FPGA-based MMC system. Background technique [0002] With the development of large-capacity long-distance flexible DC transmission technology, in order to ensure the safe and efficient operation of the DC transmission system, any short circuit on the DC line, whether it is a metallic short circuit or a high-resistance grounding short circuit, should be promptly and accurately detected. detection and removal. Taking traveling wave protection as the main protection of HVDC (High-Voltage Direct Current,) system DC line protection conforms to the fault characteristics of HVDC transmission line and has absolute advantages. Therefore, it is very important to choose an appropriate testing method for traveling wave fault protection locating device. [0003] The verification of exist...
