Description

technical field [0001] The invention relates to an intelligent integrated controller of a generating set and a control method thereof. Background technique [0002] Diesel generator sets and gas generator sets (hereinafter referred to as generator sets) are widely used in all walks of life due to their light weight, simple structure and high power density. system, peripheral support system. The engine provides power, the generator converts the power provided by the engine into electrical energy, the generator set works under the control of the control system, and the peripheral support system supports the work of the generator set. [0003] The control system of the generator set is very important in the work of the generator set. If the generator set is compared to a person, the generator set control system is equivalent to the human "brain". The power generation function of the generator set depends entirely on the "brain" of the control system to control and command. F...

Problems solved by technology

[0005] (1) In the production and manufacturing of generator sets, a large number of control connecting wires cause time-consuming, laborious, and material-intensive production of generator sets. The connected sensors on the traditional generator set controller have oil pressure sensors, high water temperature sensors, and three-phase Current transformers, three-phase voltage monitoring wires, battery voltage monitoring wires, fuel level sensors, these sensors must be connected to the controller through wires, due to the power limitation of traditional controller output digital quantities, external relays must be connected to expand the output power control The starting of the generator set and the speed of the generator set

These have greatly increased the number of devices and wires outside the controller, resulting in a large amount of man-hours and wire materials for the electrician to complete the manufacturing of the control system. From the perspective of the enterprise, on the one hand, it increases the material manufacturing cost of the generator set.

Another aspect leads to the fact that enterprises must use high-quality electricians to complete the wiring, which increases the requirements of workers, increases labor costs, increases product costs, and increases product production cycles.

[0006] (2) The reliability of the product is greatly reduced. The use of a large number of external relays, wiring, and terminal blocks makes the product very complicated. These large and complex products greatly reduce the reliability of the product. The terminal blocks of any wire If it falls off or any relay is damaged, it will cause the entire generator set to be unusable, and the wire terminal is the most prone to problems during production, transportation and use.

As a result, unforeseen failures of generator sets increase

[0007] (3) The difficulty of after-sales maintenance service and the cost of after-sales service are increased. The external wiring of different brands of engines and generator sets is different, and different users have different functional requirements for generator sets, which leads to differences in the external wiring of generator sets. Different external wiring leads to In order to avoid the cumbersome and complicated work of after-sales maintenance personnel, most of the faults of the generator set appear on the fault of the control system, and the third-generation generator set control system widely used at present cannot self-check its own fault, resulting in a simple fault problem, and the after-sales personnel have to travel long distances to the destination for simple repair work

Substantial increase in after-sales service costs of enterprises
