The invention provides a motor reactive power compensation system and method. The motor reactive power compensation system comprises at least one reactive power compensation unit, each reactive powercompensation unit is used for providing reactive power compensation for a group of asynchronous motors which are standbys of each other, and each reactive power compensation unit comprises a reactivepower compensation device, a main switch and two switching switches. The two switching switches are a first switch and a second switch. Each group of asynchronous motors which are standbys of each other comprises a first motor and a second motor. One end of the first switch and one end of the second switch are connected to the main switch. The other end of the first switch is connected to a busbarconnected to the first motor, and the other end of the second switch is connected to a busbar connected to the second motor. When the first switch is switched on, the reactive power compensation device provides reactive power compensation for the first motor. When the second switch is switched on, the reactive power compensation device provides reactive power compensation for the second motor. According to the system provided by the invention, the problems of low utilization rate and large equipment investment of an existing reactive power compensation device can be solved.
Description
technical field [0001] The invention relates to the field of electromechanical protection, in particular to a motor reactive power compensation system and method. Background technique [0002] A load device in a factory usually has two sets of power equipment, one set of equipment operates with the load device, and the other set of equipment is standby. When the operating power equipment fails or is overhauled, the backup power equipment continues to work with the load device to ensure continuous operation of the load. . [0003] Under normal circumstances, the two sets of power equipment have the same model and parameters, and they serve as backups for each other. Each set of power equipment has a set of reactive power compensation system, which can improve the power factor of the equipment and enhance the load carrying capacity through reactive power compensation. When the power equipment is running, the reactive power compensation system generates reactive power; when t...
