|Title:||Automatic control system of hydroelectric generator||Other Title:||一种水力发电机的自动控制系统||Authors:||Yang, H
|Issue Date:||2018||Source:||中国专利 ZL 201510548548.4||Abstract:||The invention relates to an automatic control system of a hydroelectric generator. The automatic control system at least comprises a battery pack, a three-phase rectifier bridge, a three-phase dummy load and a controller; when the voltage of the battery is located between upper limit voltage and lower limit voltage, the hydroelectric generator is connected with the input end of the three-phase rectifier bridge so as to charge the battery pack under the control of the controller, and the output ends of the battery pack and the three-phase rectifier bridge are connected with an external load under the control of the controller, so that power can be supplied for the external load; when the voltage of the battery pack is decreased to the lower limit voltage, the controller cuts off a closed circuit of the output ends of the battery pack and the three-phase rectifier bridge and the external load, so that power supply is stopped; and when the voltage of the battery pack is increased to the upper limit voltage, the controller cut offs a closed circuit of the hydroelectric generator and the input end of the three-phase rectifier bridge, and the hydroelectric generator is connected with the three-phase dummy load under the control of the controller so as to perform discharging. The controller of the automatic control system of the invention perform charging and discharging control on the circuits according to the voltage conditions of the battery pack; a motor and batteries are protected through the three-phase dummy load. The automatic control system has the advantages of compact structure and stable operation, and is especially suitable for hydroelectric generators.
