Based on controlling the power quality of the 6.3kV power system of a coal mine in North China, a topology consist of Passive Power Filter (PPF), Thyristor Switched Capacitor (TSC) and Fixed Compensation Capacitor (FC) has been studied. Combining the thermodynamics modeling theory with network topology analysis method, the parameters of PPF, TSC and FC was proposed and optimized. Though there is a 5.th single tuning filter only, the measured results show that the average harmonic current injected into the power system completely accord with Chinese national standard GB/T-14549-93 and the power factor is increased to 0.99 without any possibility of over-compensation or under-compensation. Due to the action of the PPF the negative effect that caused by zero-voltage-switch of TSC was eliminated by proposed topology. The study of this paper gives the corner stone of theory and method for realizing smart grid system with Chinese characteristics.
