The invention discloses a generator set parallel operation control system. The system comprises a plurality of generator sets, a plurality of unit switch cabinets, a plurality of parallel operation controllers, a plurality of excitation controllers, a plurality of relays and a lower computer assembly, and the generator sets, the unit switch cabinets, the parallel operation controllers, the excitation controllers and the relays are in one-to-one correspondence; the contact of the parallel operation controller and the contact of the excitation controller are connected in series and then are connected between the first output end of the lower computer assembly and the control ends of the unit switch cabinets, the contact of the relay is connected in parallel with the contact of the excitation controller, the coil of the relay is connected with the second output end of the lower computer assembly, and the unit switch cabinets are connected with the generator set and the bus; the lower computer assembly is used for controlling the contact of the relay to be closed or opened and outputting a closing instruction to the unit switch cabinets; the parallel controller is used for modulating the frequency of an electric signal output by the generator set and controlling the closing or opening of a contact of the parallel controller; and the excitation controller is used for regulating the voltage of an electric signal output by the generator set and controlling the on or off of the contact of the excitation controller.
Description
technical field [0001] The present application relates to the technical field of electric power generation, and in particular to a generator set parallel control system. Background technique [0002] The existing paralleling scheme of generating sets is mainly based on the quasi-synchronous paralleling mechanism, and the paralleling controller is used to directly control the connection of the first generating set to the busbar and monitor the voltage on the busbar. When the voltage on the busbar meets the quasi-synchronous paralleling condition Control the standby units to be connected to the bus, thus completing the parallel operation. However, due to the limited monitoring accuracy of the parallel controller, there is a risk of parallel failure due to asynchronous or poor synchronism during the parallel operation. Therefore, it is necessary to provide a solution that can ensure the reliability and success rate of parallel machines. Contents of the invention [0003] Th...
