Abstract

This paper presents the design, analysis and development of 30 kVAr DSTATCOM for compensation of reactive power in an 800 kW radial distribution system, feeding power to crucial loads of an educational institution. In this paper the study of radial distribution system is analyzed in terms of electrical power system of institute, power consumption pattern and tariff related issues. Made some conclusions to improve the system performance in terms of power factor and reduction in tariff. The DSTATCOM performance depends on the calculation of the reference source currents that generates the gating pulses of the voltage source converter (VSC) based DSTATCOM. For this purpose the control strategy adopted is IRP (Instantaneous Reactive Power) and SRF (Synchronous Reference Frame) theory and ADALINE is implemented in this system using MATLAB/ SIMULINK software. Generation of the PWM pulses triggers the IGBT of the VSC based DSTATCOM. This is achieved using DSP TMS 320 F 2812, a 32 bit processor that is programmed with CCS V8.0. The performance of the selected distribution system is analyzed experimentally in a hardware prototype to evaluate the effect of DSTATCOM. It is observe that the selected radial distribution system with DSTATCOM provides voltage sag mitigation, reactive power compensation and power factor improvement.
