Example Embodiment

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings:

[0027] Such as figure 1 As shown, the secondary equipment online monitoring and analysis system of the present invention includes an intra-site network switch and a zone I communication gateway machine set at the plant site, a data network zone I switch, a collection server, and an application server set at the main station; a collection server and Application servers can realize mutual backup.

[0028] Connect the secondary equipment such as the relay protection device, standby automatic switching device and low-cycle load shedding device in the substation to the network switch in the station. One signal from the network switch in the station is sent to the integrated monitoring system platform in the station, and the other signal is sent to The area I communication gateway machine, after processing the data through the area I communication gateway machine, send ...

Abstract

The invention discloses a secondary equipment online monitoring and analysis system and method. The secondary equipment online monitoring and analysis system is formed by using hardware equipment of acommunication gateway machine, a dispatching data network and the like. The plant station end I area communication gateway machine communicates with secondary equipment of a relay protection device,a backup power auto-switch-on device, a low-cycle load dropping device and the like, and transmits real-time relay protection device information and backup power auto-switch-on device and low-cycle load dropping device information to a dispatching end at the same time. The online monitoring and analysis system enables real-time monitoring on device running status through information filtering, information classification and information querying. Multi-source information is synthesized for fault diagnosis through online fault analysis, a fault report is finally formed, and a reliable judgment basis and rich fault information are provided for comprehensive intelligent alarming. Security and reliability of remote control are guaranteed. Reliable counting data are provided for running analysisand evaluation through real-time automated counting on the secondary equipment running status and running work conditions.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to an on-line monitoring and analysis system and method for secondary equipment. Background technique [0002] The Baoji area has a large power supply radius and a wide range of power supply. In the past, when the system failed, it was mostly observed and recorded manually by the on-duty personnel of the substation and then reported by telephone. The accuracy and speed were not satisfactory. In order to analyze and judge accidents, relay protection personnel urgently need on-site fault recording reports and microcomputer protection print reports. In order to obtain these information, relay protection personnel have to drive a long distance to retrieve the recording images, which is not conducive to accident handling. To a large extent, the speed of troubleshooting is restricted, and the operation and maintenance costs are high. [0003] The rapid, accura...
