Description
Technical Field
The invention relates to a power grid operation management system, in particular to a channel configuration method for rapidly positioning faults of a telemechanical management machine.
Background
With the rapid development of economy in China, cities in China have the situations of high power supply load density, complex power supply mode and higher requirements on reliability. Especially, once a telemechanical management machine in a transformer substation has an accident, large-scale users and important users in a city have great influence on the operation control. The coastal regulation and control system main station and the station are interconnected through 104 channels built by a telecontrol management machine, a front-end server, a router and an optical fiber cable. The reliability of the 104 channel between the main station and the plant station plays an important role in the operation reliability of the power grid.
In order to regulate and control the normal and efficient development of operation work, a station side telemechanical management machine of a coastal company establishes 2 104 channels with a main station side through two access network planes A and B, each channel is provided with 2 communication links, the topological structure meets the main and standby redundancy and can meet the normal requirement of the regulation and control operation work, but when the telemechanical management machine fails, one communication link of each 104 channel is interrupted, because the channel state working condition depends on the operation output of the two communication links, after one communication link is interrupted, or after the operation output, the channel is still displayed on line, the telemechanical management machine failure cannot be timely found, so that automatic operation and maintenance personnel cannot rapidly position the telemechanical management machine failure, and hidden dangers are hidden for the safe and stable operation of a regulation and control system.
Disclosure of Invention
The present invention is directed to solve the above technical problems and provide a channel configuration method for rapidly locating a fault of a telemechanical supervisor, which can ensure safe and stable operation of a regulation system.
In order to solve the technical problems, the invention adopts the following technical scheme:
a channel configuration method for rapidly positioning faults of a telemechanical supervisor comprises the following steps:
firstly, topology combing is carried out on channel connection conditions, a backbone router and a switch interface are planned for a newly added channel, and related planning is carried out in a routing table;
then configuring relevant parameters of a channel table, a communication plant station table, remote measurement, remote signaling, remote control and remote regulation;
checking whether the channel state is correct after the configuration is finished, if the channel state is correct, configuring a routing table on the front-end server, and otherwise, checking the parameter configuration and then reconfiguring;
configuring a longitudinal encryption authentication device, adding a tunnel for each channel, importing a machine-to-machine certificate and adding a corresponding strategy;
then performing ping operation on each channel, checking whether a channel service address can be ping-connected, if so, performing the next operation, otherwise, checking the channel service address and correcting;
and finally, testing the system operation condition to test whether the system can normally operate.
The invention has the beneficial effects that:
1. the channel configuration mode in the invention can quickly position the fault of the telemechanical management machine, thereby shortening the troubleshooting time of the telemechanical management machine;
2. the channel configuration mode can ensure the redundancy of channel operation, and at least can keep two 104 channels to normally operate when a telemechanical supervisor fails, so that the normal operation of a regulation and control system can be ensured;
3. the channel configuration mode can find single channel faults of the redundant channels, avoid simultaneous faults of the two channels and greatly reduce the probability of power grid communication accidents.

Detailed Description
The invention is described in further detail below with reference to the following figures and detailed description:
the channel configuration topological diagram is shown in fig. 1, each telecontrol management machine has two IP addresses, each IP address corresponds to one communication link, four communication links are redistributed, and a 104A channel is configured as a communication link corresponding to IP1 of the telecontrol management machine one; the channel 104B is configured as a communication link corresponding to the IP4 of the second telecontrol management machine, the channel 104C is configured as a communication link corresponding to the IP2 of the first telecontrol management machine and a communication link corresponding to the IP3 of the second telecontrol management machine, and specific communication links are allocated as shown in the following communication link allocation table.
| Channel | Communication link 1 | |
| 104A | IP1 | Is not configured |
| 104B | Is not configured | IP4 |
| 104C | IP2 | IP3 |
The configuration process of the channel is shown in fig. 2. Firstly, topology combing is carried out on channel connection conditions, a backbone router and a switch interface are planned for a newly added channel, and related planning is carried out in a routing table; then configuring parameters such as a channel table, a communication plant station table, remote measurement, remote signaling, remote control, remote regulation and the like; checking whether the channel state is correct after the configuration is finished, if the channel state is correct, configuring a routing table on the front-end server, and otherwise, checking the parameter configuration and then reconfiguring; configuring a longitudinal encryption authentication device, adding a tunnel for each channel, importing a machine-to-machine certificate and adding a corresponding strategy; then performing ping operation on each channel, checking whether a channel service address can be ping-connected, if so, performing the next operation, otherwise, checking the channel service address and correcting; and finally, testing the system operation condition to test whether the system can normally operate.
Since the channel state condition depends on the or operation output of the two communication links, after one of the communication links is interrupted, the channel is still displayed on line after the or operation output, in the previous channel configuration mode, the 104A channel is configured as the communication link corresponding to the IP1 of the first telecontrol management machine and the communication link corresponding to the IP3 of the second telecontrol management machine, and the 104B channel is configured as the communication link corresponding to the IP2 of the first telecontrol management machine and the communication link corresponding to the IP4 of the second telecontrol management machine, as shown in fig. 3. If the telecontrol management machine has a fault, the communication links corresponding to the IP1 and the IP2 are disconnected, and the states of the 104A channel and the 104B channel are both displayed normally; if the second telecontrol management machine has a fault, the communication links corresponding to the IP3 and the IP4 are disconnected, and the states of the 104A channel and the 104B channel are also displayed normally, so that the fault of the telecontrol management machine cannot be quickly positioned according to the channel states. In the channel configuration mode of the present invention, if the first telecontrol management machine fails, the communication links corresponding to IP1 and IP2 are disconnected, and at this time, the 104A channel state display operating mode exits, and the 104B and 104C channel state display is normal, so that the fault point can be quickly located at the first telecontrol management machine, as shown in fig. 4; if the second telecontrol management machine has a fault, the communication link corresponding to the IP3 and the IP4 is disconnected, the 104B channel state display working condition exits at the moment, and the 104A and 104C channel state display is normal, so that the fault point can be quickly positioned on the second telecontrol management machine, as shown in figure 5. Therefore, the fault of the telemechanical supervisor can be quickly positioned according to the channel states of the three 104 channels.
In summary, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can propose other embodiments within the technical teaching of the present invention, but these embodiments are included in the scope of the present invention.
