The invention discloses a diesel generating set paralleling and grid-connecting control system, including a grid-connecting main control cabinet, a paralleling control cabinet, a machine side control cabinet, a diesel generator set A, a diesel generator set B, closing and opening, and a control and monitoring module; The main controller in the grid-connected main control cabinet receives a mains failure, and uses communication to order the controller in the parallel control cabinet to send a signal to start the diesel generator set, and the controller of the side-machine control cabinet receives and After the machine control cabinet starts the model, control the diesel generator set A and the diesel generator set B to start; the present invention makes a synchronous judgment on the diesel generator set A and the diesel generator set B through the setting of the parallel control cabinet and the control cabinet next to the machine , and transmit it to the grid-connected main control cabinet according to the judgment result, so as to control the closing and opening of the outgoing switch cabinet of the parallel busbar, realize the parallel and grid-connected control of different brands of diesel generator sets, and save the time consumption of separate control ,Improve work efficiency.
Description
technical field [0001] The invention relates to the technical field of diesel generators, in particular to a parallel and grid-connected control system for diesel generator sets. Background technique [0002] Diesel generator is a small power generation equipment, which refers to the power machinery that uses diesel oil as fuel and diesel engine as the prime mover to drive the generator to generate electricity. The whole unit is generally composed of diesel engine, generator, control box, fuel tank, storage battery for starting and control, protection device, emergency cabinet and other components. When people use diesel generators in daily life, they usually use the engine, generator And the control system forms a diesel generator set. [0003] Existing diesel generating sets all control generators of a single brand, and it is impossible to carry out grid-connected and parallel control of diesel generating sets of different brands, resulting in slow control efficiency when...
