Energy saving system of dual-rotation identical electricity synchronous diesel generator set

Abstract

The invention relates to an energy-saving system of a double-speed same electrical system and synchronous diesel generator assembly, which comprises a diesel generator assembly, at least one breaker, a central control system, a function choosing module, a diesel generator assembly control module and a power switching module. A signal of the function choosing module enters the central control system which controls the on and off of the breaker by outputting a signal according to the input signal; the speed of the diesel generator assembly is controlled by the output signal of the central control system via the diesel generator assembly control module; the power which meets the requirements of the national grid is obtained from the output power of the diesel generator assembly through the power switching module. The system overcomes the problem of low efficiency of a variable-speed generator and has high overall efficiency and obvious energy-saving effects; the invention does not change the structure and working pattern of the existing generator, protects the existing investment and ensures that the project can be easily promoted.

Description

technical field [0001] The invention relates to a generator set control system, in particular to a synchronous diesel generator set control system. Background technique [0002] The marine diesel generator set is an energy conversion device that converts mechanical energy into electrical energy. The load of the diesel generator set changes. When the load is too much lower than the rated power, the fuel efficiency of the diesel engine will be greatly reduced, and the economy is very poor. But it cannot be stopped for power supply. Contents of the invention [0003] The present invention aims at the problems of low efficiency and poor economy caused by the change of the load of the current diesel generating set, and proposes an energy-saving system for a synchronous diesel generating set with double speed and same power system, without changing the structure and working mode of the original generating set On the premise that the marine diesel generator set is equipped with ...
