In a technical scheme adopted by the invention, the power station monitoring device comprises an embedded type power station controller respectively connected with an interface expansion unit, an operation unit and a monitoring unit, and the embedded type power station controller is connected with a power generator set, is connected with a main distribution board through the interface expansion unit, and is also connected with a propulsion control system. The power station monitoring device realizes automatic control of the power generator set, active power distribution, reactive power distribution, load management and system monitoring and alarming and is suitable for monitoring the power stations of various total electric propulsion ships.

Description

Technical field: [0001] The invention relates to a ship power station driven by a motor, in particular to a monitoring device for the power station. Background technique: [0002] The monitoring technology of ship power station is constantly developing with the progress of communication technology, microprocessor technology and control technology. The early stage of ship power station monitoring adopts the control method of separate devices. After that, the distributed control system appears and develops rapidly and widely in the following years. However, due to the large variety of products, the automation equipment of different ship engine rooms has poor versatility and low degree of modularization. When the design indicators change, the design workload will increase greatly. In addition, these products are one-to-one connected single-machine centralized control, or The self-enclosed distributed control composed of multiple units is independent in function and structure, a...

Problems solved by technology

[0002]The monitoring technology of ship power station keeps developing with the progress of communication technology, microprocessor technology and control technology. The control system appeared and was developed rapidly and widely used in the following years. However, due to the large variety of products, the automation equipment of different ship engine rooms has poor versatility and low degree of modularization. When the design indicators change, the design workload increases greatly. In addition, these products are one-to-one connected single-unit centralized control, or multi-unit self-enclosed distributed control, which are independent in function and structure, and their anti-destructive ability is poor. Once the system part is damaged, it will cause the entire system Paralyzed. At present, in the ship engine room automation system, the use of industrial computers, single-chip microcomputers, and PLCs is very common. Among them, industrial computers often use industrial-grade processors, because of their strong earthquake resistance, three-proof performance and anti-interference ability, they are suitable for marine environmental conditions. , but the reliability is not high. Based on the above situation, no embedded controller is used in the control unit of the ship monitoring system, so the control unit needs to occupy a large installation space, consumes a lot of power, has high requirements on environmental conditions, and is easy to These problems are more prominent on all-electric propulsion ships; in addition, in the existing power station monitoring devices of all-electric propulsion ships, the monitoring display unit generally used can only simply display the operating status of the power station, and cannot Real-time, dynamic, comprehensive and intuitive monitoring of the power station, and the casing and front baffle of the display unit are not designed to be reinforced; none of the existing power station monitoring devices for all-electric propulsion ships It comes with an independent uninterruptible power supply. When the whole ship loses power, the power station monitoring system cannot automatically start the backup diesel generator set, resulting in long-term power failure of the whole ship caused by the failure of some diesel generator sets to start.
