Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] see figure 1 figure 2 The control system of a natural gas generator set shown includes a unit controller 5, and the unit controller 5 is connected with the U, V, W three-phase connection of the power generation input of the natural gas generator set through a current transformer 1 and a fuse 4 to realize Monitoring and power calculation of the three-phase input voltage of the power generation; and through the current transformer 1 and the fuse 4 and the A, B, C three-phase connection of the mains input, the monitoring of the three-phase voltage and phase current of the mains input is realized. This is the basis for judging whether the mains power fails (input) and the calculation of power; its characteristic is that it also includes:

Abstract

The invention relates to a control system of a natural gas generator set, which comprises a set controller, and the set controller is connected with three phases U, V and W of power generation input of the natural gas generator set through a current transformer and a fuse, and is connected with three phases A, B and C of commercial power input through the current transformer and the fuse; the first ECU is used for igniting and controlling the air-fuel ratio and is electrically connected with the unit controller; the sensor arranged on an engine is electrically connected with the unit controller; the generator voltage regulating plate is used for regulating voltage and is electrically connected with the unit controller; the rotating speed sensor is used for monitoring the rotating speed in real time and is electrically connected with the unit controller; and a monitoring computer for remote monitoring is electrically connected with the unit controller. The control system is simple in structure, stable and reliable, can provide manual and automatic operation modes and five power generation modes, and can be used under various complex conditions.

Description

technical field [0001] The invention relates to a generator set, in particular to a control system of a natural gas generator set. Background technique [0002] Gas generator set is a new type of generator set developed to meet the world's environmental protection requirements and the new market environment. Gas-fired generators make full use of various natural gas or harmful gases as fuel, turn waste into treasure, operate safely and conveniently, have high cost-effectiveness, low emission pollution, and are suitable for cogeneration of heat and electricity. The market prospect is very broad. my country's natural gas resources are very rich. Compared with my country's abundant natural gas reserves, the proportion of natural gas in my country's primary energy consumption is too small, and it has the potential to increase significantly in the future. [0003] Due to the impact of natural gas supply, natural gas power generation is still in its initial stage in my country. I...
