Problems solved by technology

The existing ship power station monitoring technology can no longer meet the needs of the power supply system management
[0003] In the design of conventional ship power station monitoring system, based on the control requirements of single power station or two power stations, it is mostly designed as a distributed structure with single or double control cores, that is, the main controller of this power station only has the control function for the equipment of this power station, and cannot realize cross-power station Control management, such a control system can only realize the redundancy of dual power stations, but cannot achieve the redundancy of the control host
[0004] For the flexible and diverse power station topology in the super large ship power supply system, the management of the power supply area is beyond the scope of power station management, and the traditional design method can no longer be effectively applied

Embodiment Construction

[0051] In the following embodiments, unless otherwise specified, all the components mentioned are conventional equipment.

[0052] like figure 1 As shown, in one implementation, the management method of the present invention is used in a power supply monitoring system of a large ship, and the composition of the power supply monitoring system of the large ship is as follows:

[0053] overall composition

[0054]

[0055] Structure and interface

[0056] For the upper console, the power station control device monitoring component (area manager) and the terminal equipment of the power station monitoring console, power centralized control console, and power backup centralized console exchange information and instructions through the CAN bus network communication protocol. In consideration of reliability and modular design, the CAN bus communication network is divided into 6 subnets.

[0057] For the machine-side monitoring box, the unit controller of the power station contr...

Abstract

The invention provides a controller management method for a ship power station. The ship power station is internally provided with a plurality of power stations, wherein each power station is provided with one or more sets. The monitoring method is characterized by comprising the steps of configuring a set controller for each set, configuring a regional controller for each power station for controlling one or more sets and the corresponding set controllers of the power station, presetting a priority level for each regional manager, forming the sets in each region into a power supply echelon when the power stations operate, and controlling the power supply echelons according to the priority levels of the regional managers, wherein the priority levels of the regional managers are different. The management method puts forward distributed multilevel control system architecture design and multi-controller authority management for the first time and has a higher reliability index than the conventional power station monitoring system.

Description

technical field [0001] The invention relates to a power supply system of a ship, in particular to a monitoring and management method for a power grid used in a ship power system. Background technique [0002] However, with the large-scale development of ships, the number of power stations on ships is increasing, and the number of generating sets is also increasing. The existing ship power station monitoring technology can no longer meet the needs of the power supply system management. [0003] In the design of conventional ship power station monitoring system, based on the control requirements of single power station or two power stations, it is mostly designed as a distributed structure with single or double control cores, that is, the main controller of this power station only has the control function for the equipment of this power station, and cannot realize cross-power station Control management, such a control system can only realize the redundancy of dual power stati...
