Abstract

Provided is an alarming method of a converting station monitoring system. Two total control units in a converting station are connected with a switch machine of a station level network through network cables, data collecting equipment is connected with the corresponding switch machine, a heartbeat network which connects the two total control units is connected in through a starting end of the station level network and connected out through a tail end of the station level network; when one total control unit is in a power-loss state, the other total control unit is used by switching; when a network is in power-down fault, the switch machine corresponding to the station level network sends a power-down alarming signal to the total control units; when the network is in an abnormal non-power-down state, a heartbeat message is stopped, and the total control units which cannot detect the heartbeat of the opposite side can timely send a network abnormity alarming signal to a centralized control center.

Description

The alarm method of monitoring system of electric substation
Technical field
The present invention relates to a kind of alarm method of monitoring system of electric substation.
Background technology
The monitoring system of electric substation network is the fundamental prerequisite of realizing unattended operation transformer station, active and standby two network-bus that adopt at present many Ethernet switches, Master Control Unit 1 and Master Control Unit 2 to consist of in the station connect by " heartbeat network " between Master Control Unit 1 and the Master Control Unit 2.Utilize after the switch dead electricity self normally closed node to open as the criterion of Network Abnormal and report to the police to centralized control center, a distant place, but during the situations such as switch generation network blockage, deadlock since not yet power down normally closed node is opened realized reporting to the police.This situation is in case after occuring; although the device that is connected on the switch can send the communicating interrupt signal; but the operations staff can not tell rapidly Network Abnormal or device is unusual, and the maintainer also can't prepare concrete standby redundancy before rushing towards the scene, lose time.In addition, transformer station is in single network operation state in this situation, in case standby net occurs unusually in the process that searches problem, will cause transformer station's forfeiture monitoring." heartbeat message " is the criterion that Master Control Unit carries out the two-shipper switching in the existing transformer station, and it is the height conversion level that continues, and sent by the 3rd port of Master Control Unit.When setting up network, the 3rd port of two Master Control Units connected, judge with this whether the other side is online.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of alarm method of monitoring system of electric substation, the method is practical, report to the police effective, realized the Real Time Monitoring to station level network in the transformer station, except sending the warning when the network appliance power-down, when Network Abnormal occurring, also can in time send alerting signal to the centralized control center, make the maintainer can find out immediately unusual equipment, prepare in advance spare part, solve a problem promptly, effectively reduce the possibility that the abnormality processing time reaches the transformer station's forfeiture monitoring that causes thus.
The present invention is achieved in that
1, two Master Control Units in the transformer station are connected by the switch of netting twine with the station level network, data acquisition equipment is connect on the corresponding switch, the heartbeat network of two Master Control Units of connection is picked out by end by the top access of station level network again;
2, when one of them Master Control Unit dead electricity, switch to another Master Control Unit;
3, when the power down fault appears in network, the switch that the station level network is corresponding sends the power down alerting signal to Master Control Unit;
4, non-power-failure occurs when unusual when network, " heartbeat message " stops, and the Master Control Unit that can't detect the other side's " heartbeat " will in time send the Network Abnormal alerting signal to the centralized control center.
The invention has the beneficial effects as follows: practical, successful, realized the Real Time Monitoring to station level network in the transformer station, except sending the warning when the network appliance power-down, when Network Abnormal occurring, also can in time send alerting signal to the centralized control center, make the maintainer can find out immediately the abnormal alarm reason, prepare in advance spare part, solve a problem promptly, improve maintenance efficiency, effectively reduced the abnormality processing time and the possibility of transformer station's forfeiture monitoring of causing thus.
Description of drawings
Fig. 1 is wiring diagram of the present invention.
Embodiment
As shown in the figure, the alarm method of this monitoring system of electric substation, concrete steps are as follows:
1, two Master Control Units in the transformer station is connected with the switch 3 of station level network 2 by netting twine, data acquisition equipment 4 is connect on the corresponding switch 3, the heartbeat network 1 that connects two Master Control Units (Master Control Unit I, Master Control Unit II) is picked out by end by the top access of station level network 2 again, and namely the interface by first switch 3 enters, gone out by the interface of last switch 3;
2, when one of them Master Control Unit dead electricity, switch to another Master Control Unit;
3, when the power down fault appears in network, the switch 3 of station level network 2 correspondences sends the power down alerting signal to Master Control Unit;
4, non-power-failure occurs when unusual when network, " heartbeat message " stops, and can't detect the other side's's " heartbeat " Master Control Unit and will be in time 5 sends the Network Abnormal alerting signal to the centralized control center.

Claims (1)

1. the alarm method of a monitoring system of electric substation is characterized in that:
1.1, two Master Control Units in the transformer station are connected by the switch of netting twine with the station level network, data acquisition equipment is connect on the corresponding switch, the heartbeat network that connects two Master Control Units is picked out by end by the top access of station level network again;
1.2, when one of them Master Control Unit dead electricity, switch to another Master Control Unit;
1.3, when the power down fault appears in network, the switch that the station level network is corresponding sends the power down alerting signal to Master Control Unit;
1.4, when network non-power-failure occurs when unusual, " heartbeat message " stops, the Master Control Unit that can't detect the other side's " heartbeat " will in time send the Network Abnormal alerting signal to the centralized control center.
