In this paper, the authors propose a method for computing equivalent three-phase voltage flicker using Field-Programmable Gate Array (FPGA) based Integrated Circuit (IC) to measure the instantaneous voltage vectors. The very high-speed integrated-circuit Verilog Hardware Description Language (VHDL) is used to design scheme, which provides high flexibility and technology independence. The instantaneous voltage vector module, management module and quantification modules are developed to simulate the entire system. Some novel IP (Intellectual Property) cores, such as CORDIC and FFT are introduced and adopted.
