Description

Generating set Intelligent integrated formula controller and control method thereof
Technical field
The present invention relates to a kind of generating set Intelligent integrated formula controller and control method thereof.
Background technology
Diesel generating set is lightweight with it with jet dynamic control (hereinafter referred to as generating set), simple in construction, power density are widely used in greatly in all trades and professions, the generating set sold on market is made up of four major parts, electromotor, electromotor, control system, peripheral support system.Electromotor provides power, and the power that electromotor provides electromotor is converted into electric energy, and generating set is operated under control of the control system, and the work of generating set is played a supportive role by peripheral support system.
The control system of generating set is extremely important in the work of generating set, if if generating set is compared to a people, gen-set control system is equivalent to " brain " of people.The performance of generating set generating function controls commander by control system this " brain " entirely.From the point of view of the development course of whole gen-set control system, gen-set control system experienced by three generations, the Purely mechanical control system of the first generation, the electrified control system of the second filial generation, and the unmanned type of the third generation possesses the control system of remotely control.Function is by single to comprehensively, and structure is from simple to complex.The control system of third generation generating set is with generator set controller as core, additional relay, electric fuse, connecting terminal block, each sensor and executor, communication interface, and controls connecting conducting wire in a large number what each part mentioned above linked up.Now widely used gen-set control system is third generation control system.
