Title: CONTROL METHOD SUITABLE FOR AUTONOMOUS GRID CONNECTION COORDINATION OF DIESEL GENERATOR GROUP
Abstract:
A control method suitable for the autonomous grid connection coordination of a diesel generator group. The method comprises: using a CAN bus to connect all diesel generator groups requiring grid connection inside a region so as to form a CAN network; completing the priority configuration of network nodes by means of the uniqueness of the CAN node addresses of diesel generators; the network nodes competing for a grid connection license according to the grid connection working states thereof and the grid connection working states of the other diesel generators and in accordance with a pre-set priority, wherein a network node with a lower priority exits automatically, and a network node with the highest priority obtains a grid connection right; and after a diesel generator which obtains the grid connection right completes grid connection, diesel generators not subjected to grid connection reapplying for and competing for the grid connection license until the grid connection of all the network nodes is successful. By means of the method, no special main grid connection controller is required in practical applications to coordinate various diesel generator nodes, and the nodes can be coordinated autonomously, such that the cost is reduced, and the grid connection speed is increased.
