Embodiment Construction

[0032] The parallel control device for diesel generators includes multiple controllers, each controller independently controls a diesel generator; it also includes an execution module pb containing a grid bus circuit breaker, and the contacts of the grid bus circuit breaker in it are connected to Between the grid busbar and the load; the controller includes a processor, and the input of the processor is connected to a grid measurement module for collecting grid busbar voltage (VA, VB, VC), current (IA, IB, IC), and frequency. To collect the voltage of the controlled diesel generator (D k A.D k B.D k C), current (I k A. I k B. I k C), frequency, oil temperature t k , oil pressure p k , speed n k The measurement module is a first phase detection module used to collect the phase difference between the grid bus and the controlled diesel generator, and a second phase detection module used to collect the phase difference between the controlled diesel generator and the synchro...

Abstract

The invention relates to a diesel generator control device, in particular to a diesel generator parallel control device. The invention solves the defects and problems caused by the distributed control mode in which one controller collects and controls multiple diesel generators in the existing diesel generator controller. The present invention adopts a control mode in which each controller independently controls a diesel generator and each controller is a bus structure. A field bus communication module and a phase detection module are added on the basis of the existing controller hardware. In terms of software, the fault rearrangement method is adopted when the unit is started, and the power is evenly distributed according to the power distribution algorithm when the power is distributed. When installing a circuit breaker, it is necessary to confirm that the controller is in normal working condition. The circuit breaker between the power grid and the load adopts an independent execution module. It provides great convenience for system capacity increase or decrease.

Description

technical field [0001] The invention relates to a diesel generator control device, in particular to a diesel generator parallel control device. Background technique [0002] With the steady improvement of the national economy, more and more departments have put forward higher requirements for the continuity of power supply. Existing diesel generator controllers can generally meet the requirements of single-machine or double-machine control, and more than two-machine systems need to design a dedicated controller, and the control system mostly adopts a distributed control method (one controller controls multiple diesel generators). Use the state diagram as figure 1 As shown (take the three machines as an example), its internal structure diagram is as follows figure 2 shown. The existing controller includes a processor, and the input of the processor is connected to a grid measurement module for collecting grid bus voltage (VA, VB, VC), current (IA, IB, IC) and frequency, a...
