Description

Technical field: [0001] The invention relates to a control system for adjusting the operating frequency of a diesel engine in power generation equipment, in particular to an automatic frequency conversion energy-saving electronic speed regulation control system applied to conventional generating sets. Background technique: [0002] At present, conventional generator sets work at a fixed speed of 50Hz or 60Hz. Even under light load, the diesel engine is still running at high speed, which will inevitably lead to increased wear of the diesel engine and waste of fuel. When working under changing load conditions, diesel engines often run under very light loads and then stand by. [0003] The power load in our country is designed according to the electromagnetic parameters of AC 50HZ. Simply reducing the frequency will reduce the inductive reactance of the inductive load and easily damage the equipment. The diesel engine and generator in the prior art adopt the connection mode of ...
