Thyristor Switched Filter is an effective reactive compensation and harmonic filter device, but its performance largely depends on the control strategy. According to the characteristics of injection molding machine in project, in view of the various disadvantages of existing control strategies, a new control strategy and corresponding multi-objective optimal design method for TSF based on Particle...
A TAPF device consisting of Active Power Filter and Thyristor Switched Filter is presented in this paper to balance filtering effect, device capacity and economic benefit. Firstly, the dynamic model of the TAPF system is established under the condition of harmonic current according to the Norton's theorem, and the resonance between the TAPF and the power grid is analyzed. Then the expressions of the...
With the progress of industry, power electronic equipments have been widely used in power systems, but the nonlinear characteristics of these equipment have produced serious harmonic/interharmonic pollution. They can result in the malfunction of remote control systems, light flicker, and communication interference. This makes harmonic/interharmonic analysis an important topic in power quality. In...
