Water-cooled power monitoring device with transient monitoring capability

Abstract

The invention designs a water-cooled power monitoring device with a transient monitoring capability. A functional panel is used for controlling, displaying and alarming an electric power monitoring device, displaying the on-off state and alarm information of the electric power system protection switch sent by a programmable logic controller, and outputting the on-off control information of the electric power system protection switch to an input andoutput module; a sensor module is used for measuring operation parameters of the power system; the programmable logic controller completes acquisition of operation state information of the power system protection switch and linkage protection information processing of the protection switch through the input and output module, exchanges information with a computer, and outputs a power system network topology structure and alarm information to the function panel. The water-cooled power monitoring device integrates the functions of real-time information monitoring, power supply and distribution network control, fault diagnosis, alarm, noise reduction and the like, realizes centralized management of a power system, and ensures stable and reliable operation of the power system.

Description

technical field [0001] The invention belongs to the technical field of ship power monitoring, in particular to a water-cooled power monitoring device with transient monitoring capability. Background technique [0002] Civilian ship power system monitoring equipment has a large number and scattered functions, and there are many types and forms of external interfaces of the equipment, which is not convenient for centralized monitoring of information; at the same time, various monitoring information cannot be monitored in real time and synchronously, making it difficult for operators to fully grasp the monitoring nodes of the system Status information at the same time; each monitoring equipment does not have the ability to monitor the transient information of the power system, cannot complete the analysis of the transient characteristics of the power system, and does not use intelligent analysis measures to realize the fault diagnosis of the power system; in addition, because ea...

[0002] Civilian ship power system monitoring equipment has a large number and scattered functions, and there are many types and forms of external interfaces of the equipment, which is not convenient for centralized monitoring of information; at the same time, various monitoring information cannot be monitored in real time and synchronously, making it difficult for operators to fully grasp the monitoring nodes of the system Status information at the same time; each monitoring equipment does not have the ability to monitor the transient information of the power system, cannot complete the analysis of the transient characteristics of the power system, and does not use intelligent analysis measures to realize the fault diagnosis of the power system; in addition, because each monitoring equipment uses The forced air cooling method, on the one hand, is not conducive to the control of the air quality in the ship's interior cabin, on the other hand, it also increases the difficulty of controlling the ambient temperature in the cabin, increases the load of the air conditioner, and is not conducive to the ship's vibration and noise reduction, energy saving and emission reduction.
