Abstract: The proliferation of power electronics -based industrial and domestic equipment which has degraded thepower quality in power distribution networks due to non-linear load impedance.The Distribution STATic COMpensator(DSTAT-COM)has proved to be a useful custom power device to eliminate harmonic components and to compensate reactive power for balanced/unbala nced linear/nonlinear loads. This paper presents a novel control strategyto calculate the reference compensation current of three phase DSTATCOM under distorted utility condition at instantaneous state. In this proposed approach a digital PI controllerhas been implemented on FPGA to make the process faster and enable the design to be independent of process technology .The performance of the system simulated in Matlab Platform and evaluated considering the source current total harmonic distortion. The VHDL design has be en implemented using ISE10.1 tool from Xilinx. This is tested on a board with hardware configuration such as FPGA-XC2VP4 with on chip PowerPC-405 Processor, ADC AD9240-14 bit 10MSPS analog input channel,DAC AD7541-12-bit of conversiontime– 100ns with System clock 40 MHz
