Embodiment Construction

[0030] The diesel generator parallel control system includes a grid controller and multiple diesel generator controllers, each diesel generator controller independently controls a diesel generator set; the grid controller includes a first processor, and the input of the first processor The end is connected with a power grid measurement module for collecting grid bus voltage (VA, VB, VC), current (IA, IB, IC), frequency, and phase, and the output end of the first processor is connected with a first execution module. The module controls the grid bus circuit breaker PB, the contact of the grid bus circuit breaker PB is connected between the grid bus and the load, and the first processor is also connected with a field bus communication module, a host computer communication bus module, a liquid crystal display module, and a protection module; The diesel generator controller includes a second processor, and the input of the second processor is connected with a connection for collecti...

Abstract

The invention relates to a diesel generator control device, in particular to a diesel generator parallel control system. The problem of high hardware cost and relatively complex software structure of the existing diesel generator parallel control device is solved. On the basis of the patent 201510461567.3, the present invention adds a power grid controller, reduces the power grid parameter detection module and two phase detection modules and other hardware on the diesel generator controller, and changes the software control method accordingly, ensuring the reliability of the system The premise of operation reduces the hardware cost and makes the control method simpler.

Description

technical field [0001] The invention relates to a diesel generator control device, in particular to a diesel generator parallel control system. technical background [0002] The Chinese patent No. 201510461567.3 discloses a diesel generator parallel control device, which is improved on the basis of the original single controller controlling multiple machines. Although this patent can realize automatic switching of the number of units on the diesel generator bus as the load changes. However, the hardware cost of the controller in the control device is relatively high, and it not only needs to monitor the state of the grid, but also monitors and controls the diesel generator set, and the software structure is relatively complicated. Contents of the invention [0003] The invention solves the problems of high hardware cost and relatively complicated software structure of the existing diesel generator parallel control device, and provides a diesel generator parallel control s...
