In this research, a storage system, suitable for the power system of construction, is proposed and optimized. The storage system mainly consists of control system, converter, flywheel and motor. This system can release the pressure of the power grid during the on-peak period and supply the consumers with cheap energy. This research is going to analyze the characters of the system and then adjust its structure to the architecture.
In order to get the stable output, the small switch pressure resistance and the high power factor with the high power three-phase rectifier, the three-phase VIENNA PFC circuit topology was studied, and the principle of VIENNA rectifier was investigated, based on the original concept of the control method, the interval control with hysteresis control method were used to control the whole rectifier circuit. Throughout the system design had been completed, the MATLAB model is built for the design of the circuit simulation, the simulation results show that the system output is stabilizing output, and the pressure resistance of the switch device is half of the output voltage, and the input power factor is 1.And set up some small prototype to verify the control method of the rectifier.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
