A high-voltage SVG individual phase control system based on an FPGA soft core comprises an FPGA soft core, a PLL (Phase-Locked Loop) and a logic signal processing module. The FPGA soft core, the PLL and the logic signal processing module are integrated into an FPGA chip. The FPGA soft core is used to run a software code, and includes a CPU, a JTAG debugging interface, an RAM memory, an IO port, anEPCS controller and a system bus. The PLL provides a working clock for the FPGA soft core and the logic signal processing module after locking and frequency-doubling an externally input clock signal.The logic signal processing module includes a PWM (Pulse Width Modulation) module, a code transmitting module TX, a code receiving module RX, a protection processing module and a parallel bus interface, and is used to communicate with the CPU, the memory and a peripheral controller of the FPGA soft core. The architecture of the high-voltage SVG individual phase control system is greatly simplified, the software and hardware of the high-voltage SVG individual phase control system are programmable, and the anti-interference ability of the control system is improved.
Description
technical field [0001] The invention relates to the field of power SVG equipment control, in particular to a high-voltage SVG phase-splitting control system based on an FPGA soft core. Background technique [0002] High-voltage SVG (Static Var Generator) is the most advanced reactive power compensation technology in the current power system. The high-voltage SVG power unit adopts a chain structure, and each phase is composed of several power units cascaded. The number of cascaded power units per phase of high-voltage SVG is determined according to the voltage level of the power grid. For example, 35kV star-connected SVG has 36-40 power units per phase. How to generate so many power unit control signals and means is high-voltage SVG phase separation key to the control system. [0003] At present, the mainstream technology of high-voltage SVG phase separation control system is "DSP+FPGA", DSP such as TMS320F2812, TMS320F28335, ADSP-21489. Although DSP has rich peripherals an...
