In the process of design of electric vehicle control system, the response of each control node in the charging process is analyzed, then the control strategy of the charging process of vehicle on-board charging system is studied and designed according to the electric vehicle on-board charging system structural characteristics, with reference to the national standard of the electric vehicle conduction...
Two control strategies are implemented for multiterminal voltage sourced converter (VSC)-based HVDC (M-VSC-HVDC). A test system consisting of five terminals was developed in PSCAD. In-Strategy 1, the Predictive controller is implemented in the inner control loop whereas strategy 2 using proportional-integral-derivative controller (PID). Small signal analytical models for two terminal VSC-HVDC are...
The purpose of this research is to optimize control and enhance performance for a variable speed constant frequency (VSCF) doubly-fed induction generator (DFIG) wind turbine generation system by using fuzzy logic controller. The control of the rotor-side converter is realized by stator flux oriented control and the fuzzy controller performs robust speed control. The control of the grid-side converter...
In this paper, three different system topologies for dynamic voltage restorers (DVRs) are modeled and tested using Simulink's SimPowerSystem Toolbox for power system quality studies. The DVR controls are based on hysteresis voltage control. Simulation tests on radial distribution system, equipped with the DVR under three-phase and single-phase voltage sags with phase jump, are used to verify the operation...
This paper presents the state of the art in the field of three-phase voltage source PWM rectifier with reduced input harmonics and unity power factor. The working principle, modeling procedure, corresponding control strategy as well as typical waveforms are introduced in detail which can provide some guidelines for engineers to analyze design and implement
