Abstract

The invention relates to an automatic grid-connected control system for a power generator set. The power generator set comprises a power generator and an engine which are mutually connected, wherein the power generator is connected to a load through a parallel computer circuit breaker. The control system comprises a microcomputer controller for receiving an external signal; a switch controller, a speed adjustor and a sensor are arranged between the microcomputer controller and the engine; a voltage adjustor is arranged between the microcomputer controller and the power generator; and the microcomputer controller is connected to the parallel computer circuit breaker through a closing and opening relay. The automatic grid-connected control system has the benefits that the control process of a digital parallel computer of the power generator set is realized by utilizing the microcomputer controller, the startup, the parallel computer operation and the power supply process of the power generator set are automatically finished, and all human judgment and all manual operation are realized by the microcomputer controller, so that the parallel computer system is simplified, the power supply recovery time is shortened, and the reliability of equipment operation is improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of generating sets, in particular to an automatic grid-connected control system for generating sets. Background technique [0002] Ordinary diesel generator set parallel control is mainly composed of: generator set control module, synchronization module, generator bus power supply module, load distribution module, parallel circuit breaker module, protection relay module, etc., but so many independent modules are mutually The wiring and mutual control of the system is very complicated, with high failure rate and poor practicability. With the development of the electronic industry, the technology of paralleling generator sets by using PLC and relay protection control has appeared successively, but it is highly specialized and poor in reliability, so it cannot be popularized. Contents of the invention [0003] In order to solve the above problems, the present invention provides an automatic grid-connected co...
