Parallel diesel engine power generator system and control method therefor

Abstract

The present invention relates to a parallel diesel engine power generator system and a control method therefor. The present invention comprises: a plurality of diesel engine power generators connectedin parallel to each other; a power distribution unit which collects power generated by each of the diesel engine power generators, and to which an external load is connected; engine output detectionunits which detect an output side RPM of a diesel engine and configure the diesel engine power generators, respectively; automatic voltage regulators provided in power generators configuring the diesel engine power generators, respectively; engine power generator control units for connecting electronic control units, which configure the diesel engine power generators, respectively, with the engineoutput detection units and the automatic voltage regulators, so as to control the diesel engine power generators; and a system control unit to which respective engine power generator control units ofthe diesel engine power generators are connected, wherein the power distribution unit is connected to the system control unit so that the system control unit distributes a load applied to the power distribution unit according to respective performance indices of the diesel engine power generators, so as to control the engine power generator control units. The present invention can increase the efficiency of power generation output from a plurality of diesel engine power generators connected in parallel and extend the lifetime of a diesel engine power generator.

Description

technical field [0001] The invention relates to a parallel diesel engine generator system and a control method. Background technique [0002] With the sharp increase in electricity consumption and difficulties in electricity production, the demand for self-generated electricity is increasing not only domestically but also around the world. [0003] Especially domestically, the need for self-generated electricity is increasing because of peak-value calculations and the application of weighted values ​​that increase with usage, resulting in electricity charges that can increase by up to five times the basic charge. In order to realize self-generation, generators using diesel engines are being used recently. [0004] Generators using diesel engines are divided into mechanical engine generators and electronic engine generators. [0005] Mechanical engine generators are less expensive than electronic engine generators, but have lower fuel efficiency and performance, and have di...

AI Technical Summary

Problems solved by technology

However, since diesel engines are recovered from scrapped diesel vehicles to manufacture diesel generators, when multiple diesel generators are connected, the performance and life of each diesel engine of scrapped cars are different. When there is one The life of the diesel engine generator ends or the performance drops sharply, which leads to the problem that the entire diesel engine generator cannot fully perform
