Distributed ship power monitoring system and method based on synchronous acquisition

Abstract

The invention provides a distributed ship power monitoring system and method based on synchronous acquisition, a high-precision timing technology is adopted, distributed monitoring of transient and steady-state operation parameters of a ship power system is achieved, and synchronism and a centralized display function of all monitoring parameters are guaranteed. According to the invention, all information is displayed on a distributed ship power monitoring system host in a centralized manner through distributed measurement, acquisition, centralized display and management of a power system, so that the functions of interlocking protection, power-loss continuous working and the like of the power system are realized; and an information comprehensive integration technology is adopted, so that the information integration level and the automation degree are improved, and information integration, distributed control and centralized management of the power system are realized. According to the invention, a ship control circuit is optimized by using a distributed control technology, ship cabin-penetrating cables and monitoring equipment interfaces are reduced, complexity is reduced, reliability and redundancy of control are increased, and stable and reliable operation of a power system is guaranteed.

Description

technical field [0001] The invention belongs to the field of automatic control technology and communication technology, and in particular relates to a distributed ship power monitoring system and method based on synchronous acquisition. Background technique [0002] With the continuous improvement of the level of ship electrification, the number of equipment in the ship's power system has increased sharply, and the equipment that needs to be monitored, controlled and protected has increased accordingly. In addition, the expansion of the ship's power system also puts forward higher requirements for the control and protection logic of the power system. At the same time, the increase of monitoring points in the power system puts forward higher requirements for the monitoring system. The use of a centralized monitoring system for monitoring will bring problems such as many penetrating cables, bulky equipment, high requirements for hardware resources of monitoring equipment, man...

AI Technical Summary

Problems solved by technology

The use of a centralized monitoring system for monitoring will bring problems such as many penetrating cables, bulky equipment, high requirements for hardware resources of monitoring equipment, many interfaces of main monitoring equipment, and low fault tolerance of monitoring equipment; using a distributed monitoring system will bring various problems. Real-time synchronization between monitoring devices is impossible, and monitoring data is difficult to provide effective support for power system fault analysis.
