Ship energy management system based on hot redundancy controllers

Abstract

The invention discloses a ship energy management system based on hot redundancy controllers. The ship energy management system comprises a master controller used as a main control station and further comprises a standby controller used as a standby control station. The hot redundancy controllers are adopted for conducting real-time synchronous communication through a synchronous bus. Unit controllers and unit interface modules are connected through field buses. The unit controllers are connected with main units which are connected with a main power grid through main switches. The main power grid is connected with a daily use power grid through a power supply switch. The daily use power grid is connected with a mooring unit and shore power through a power supply switch. Synchronous modules are arranged on the power supply switches. All the functions of the ship energy management system are achieved through the hot redundancy controllers, the load rates of the units and the states of the main switches can be monitored in real time, so that the generator overload situation caused by sudden changes of the loads is prevented, the phenomenon that ship safety is affected due to the power off of a whole ship is prevented, and the ship energy management system is excellent in performance, safe, reliable, convenient to operate and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of ship automation, and specifically relates to a ship energy management system based on a thermal redundancy controller, which is suitable for various electric propulsion ships, especially for special electric propulsion ships with high reliability requirements and equipped with DP2 / DP3. Such as pipe-laying ships, cable-laying ships, etc. Background technique [0002] With the increasing capacity of the ship power grid, the configuration of ship power stations is becoming more and more complex, especially in electric propulsion ships, the reliability and safety of ship energy management systems have always been the focus of attention of ship owners, design institutes and classification societies In the past, the energy management system usually used a single-controller PLC as the main controller of the energy management system. When the main controller fails, the management operation of the ship power stati...

[0002] With the increasing capacity of the ship power grid, the configuration of ship power stations is becoming more and more complex, especially in electric propulsion ships, the reliability and safety of ship energy management systems have always been the focus of attention of ship owners, design institutes and classification societies In the past, the energy management system usually used a single-controller PLC as the main controller of the energy management system. When the main controller fails, the management operation of the ship power station can only be completed manually. Shutdown maintenance replacement parts
