Abstract

The invention provides a diesel engine control system, a control method and a controller. The system includes a diesel engine, an asynchronous motor, a rectifier, a charging device and a controller. The controller is used to control the on-off of the charging device according to the current speed of the diesel engine. When the current speed is lower than the first preset speed, the charging device is controlled to charge the supporting capacitor of the rectifier, and when the voltage value of the supporting capacitor meets the preset condition, the rectifier is controlled to provide three-phase alternating current for the asynchronous motor, so that the asynchronous motor works at Under the working condition of the electric motor, it drives the diesel engine to work. The above-mentioned diesel engine control system adopts asynchronous motor, does not need a special starter motor to drive the diesel engine to work, and realizes the monitoring of the working state of the diesel engine through the controller, which not only saves space, but also realizes the automatic control of the system.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of diesel engines, in particular to a diesel engine control system, control method and controller. Background technique [0002] Diesel generator set is a kind of power equipment that uses diesel engine as the prime mover and drives synchronous generator to generate electricity. The starting performance of the diesel engine in the diesel generator set is very important to the usability of the diesel engine. The poor starting performance is time-consuming and laborious, which seriously affects the normal use of the diesel engine. [0003] Since the diesel engine cannot turn from a static state to a working state by itself, an external force must be used to rotate the crankshaft until the crankshaft reaches the necessary speed for the diesel engine to start burning. At present, a starter motor is usually used to drive the diesel engine into a working state during the start-up phase o...
