Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, it is a main flow chart of an interval measurement and control function deployment method. A deployment method of an interval measurement and control function of an intelligent substation is carried out in cooperation of manual deployment and automatic deployment and comprises the following steps:
In order to realize the cooperative execution of manual deployment, automatic deployment among multiple devices, manual deployment and automatic deployment, state settings are added for each interval, which are respectively as follows: running, hot standby, cold standby and non-running state.
Each cluster measurement and control device can be deployed with a plurality of intervals, and measurement and control functions of the plurality of intervals are realized. When the measurement and control functions of an interval are deployed from one measurement and control device to another measurement and control device, the measurement and control functions are called "migration", and as shown in fig. 2, the migration schematic diagram of the measurement and control functions of an interval is shown. Manual deployment and automatic deployment are two ways to implement migration.
And 2, electrifying and initializing. And the management program of each device is set based on the state parameter file, so that the initial deployment of the interval parameters and the measurement and control program in the container is realized, and the corresponding measurement and control program is started.
When the device is initially powered on, the device management program reads the state parameters of each interval, deploys the measurement and control programs of the intervals of the 'running' state and the 'hot standby' state and respective parameter files in a container, and starts the corresponding measurement and control programs to realize initial deployment of interval information. Each container is deployed with information of one interval, and item files generated by the interval are stored in the container, each container can be operated independently, the containers are not influenced mutually, and the independence of logic measurement and control is guaranteed. The running state of the corresponding parameter file and the program can be checked by entering different containers of the device. Meanwhile, in order to ensure that the parameters of the 'operation' state interval are consistent with the parameters of other devices, items generated by the 'operation' state interval and the modified parameter file are updated to other devices in real time through the station control layer network.
In order to realize seamless switching of the measurement and control functions, an interval measurement and control program of 'operation' and 'hot standby' is started simultaneously. In the operation process, in order to ensure that the measurement and control function of the interval is realized only by the measurement and control program of the 'operation' state interval, in the uplink data, the measurement and control program of the 'operation' and 'hot standby' state interval sends the data information and the current state of the interval to the monitoring background through the IEC61850-MMS service, and the monitoring background obtains the 'operation' state interval data according to the interval state. In the downlink data, the measurement and control program judges whether to issue the GOOSE based on the current state of the interval, if the interval is in the 'running' state, the GOOSE is issued, otherwise, the GOOSE issuing is terminated. By starting the measurement and control programs of the 'running' and 'hot standby' state intervals simultaneously and ensuring that the measurement and control programs of only the 'running' state intervals realize the measurement and control functions of the intervals, the uniqueness of the measurement and control functions of the intervals is ensured, the migration speed is improved, and the seamless switching of the measurement and control functions is realized. Fig. 3 is a diagram of a monitoring system for logic measurement and control of "running" and "hot standby" state intervals.
And 3, judging whether the main control device exists, if so, turning to the step 5, and if not, turning to the next step.
In the device operation process, in order to realize automatic deployment of multiple devices and cooperation of the multiple devices and manual deployment, a main control device needs to be determined, a heartbeat message and a manual deployment message are obtained by the main control device, and a final deployment scheme of the manual deployment and the automatic deployment is analyzed and determined. In automatic deployment, the master control device obtains the state of each interval through a station control layer network, and analyzes and determines a measurement and control function redeployment strategy; in manual deployment, the master control device monitors the manual deployment result, adjusts the manual deployment according to the needs, and issues the final deployment result.
And 4, determining the master control device for monitoring the state of each interval by comparing the priority parameter and the IP address of the device.
In the operation process, if the master control device does not exist, the device broadcasts the request management authority, after receiving the message of requesting management by other devices, the priority and the IP address of the device are compared, the device with the high priority and the small IP address is used as the master control device, and if the message of requesting management by other devices is not received, the device is used as the master control device after a period of time, so that the uniqueness of the master control device is ensured. When the main control device operates abnormally, other devices determine the main control device according to the same mode, and perform state monitoring of each interval and issue a deployment command. In all cluster measurement and control, there is one and only one master control device. Fig. 4 shows a flowchart for determining the master control device, which specifically includes the following steps:
step 4.1, when the non-master control device can not obtain the deployment message sent by the master control device within the set time, the non-master control device requests the management authority in a broadcasting mode through the station control layer network;
step 4.2, judging whether request messages of other nodes are received or not, if so, turning to the next step, if not, judging that no other node requests in preset time, determining that the node obtains the management authority, and turning to step 4.4;
step 4.3, comparing the priority of the device with the IP address, wherein the priority is high and the IP value is small, so as to obtain the management authority;
and 4.4, entering a management process, receiving and processing the heartbeat message, executing state monitoring, executing a scheduling strategy, and turning to the step 4.1.
Step 5, the master control device obtains the message, and determines whether the message is a deployment message or a heartbeat message through message analysis; if the message is deployed, the step 8 is carried out, and if the message is a heartbeat message, the next step is carried out.
The master control device obtains the messages sent by each device through the station control layer network, analyzes and processes the obtained messages and determines the types of the messages.
And 6, judging whether the abnormality exists, if not, turning to the step 5, and if so, turning to the next step.
And 7, automatically deploying according to the interval state change.
The automatic deployment is that the main control device monitors the state of each device, determines the migration strategy and sends an execution instruction by the main control device. And the management program of each device redeployes the measurement and control function of the interval according to the obtained state.
When automatic deployment is performed, the management program of the main control device monitors the running state of each interval, such as CPU load, memory usage and the like, and forms a deployment condition. In order to cooperate with manual deployment and realize the constraint of manual deployment on automatic deployment, the master control device simultaneously monitors the states of the interval settings. In the operation process, when the cluster measurement and control device is found to be overloaded, abnormal in state and the like, namely the deployment state of each interval is determined again through analysis and processing according to the current state distribution of each interval, and the deployment result is sent to each device in a broadcast mode through a station control layer network. And the management program of each device redeploys interval parameters according to the acquired deployment message, starts and stops the corresponding measurement and control program or GOOSE to issue, realizes redeployment of interval measurement and control functions, and stores the current state into a specific parameter file. Meanwhile, the management program of each device monitors the execution state of the device and ensures the correct execution of the issued command. The flow chart of automatic deployment is shown in fig. 5, and specifically includes the following steps:
step 7.1, the master control device receives the heartbeat message;
7.2, judging whether an abnormal state exists, if so, turning to the next step, and if not, turning to the step 7.1;
7.3, judging whether the migration condition is met, if so, turning to the next step, and if not, turning to the step 7.1;
7.4, analyzing and determining a deployment strategy;
7.5, the main control device issues a migration command;
7.6, reading and storing the task table by the target device;
7.7, executing migration;
and 7.8, after the migration is finished, issuing a heartbeat message according to the new state, and turning to the step 7.1.
Considering the operation of the measurement and control program of the 'hot standby', the state conversion of the 'cold standby' and the 'operation' or the 'hot standby' is different from the conversion of the 'hot standby' and the 'operation'.
(1) And (3) switching between the running state and the hot standby state, modifying the state of the interval by a management program of the device, and issuing by a monitoring program start-stop GOOSE.
(2) The conversion between the cold standby state and the running state or the hot standby state is realized by deploying interval parameters and a measurement and control program by a management program and starting and stopping the corresponding measurement and control program.
And 8, carrying out manual deployment.
And manual online deployment is realized by setting the state on the operation and maintenance interface. In order to realize the cooperativity of manual deployment and automatic deployment and improve the reliability of the manual deployment, the main control device is used as a final decision center of the manual deployment.
In the operation process, the manual deployment modifies the state of each interval through the operation and maintenance interface, when each device receives the deployment state sent by the operation and maintenance interface, the state result is not immediately executed, but is sent to the main control device, the state result is analyzed by the main control device and then sent to each device, each device management program realizes the deployment of interval parameters and the starting and stopping of the measurement and control program or the GOOSE release according to the obtained interval state, and the parameter deployment result is stored in a parameter file. If the result obtained by the main control device does not meet the actual requirement, the main control device can automatically adjust the deployment mode according to the setting result and the current state of other devices so as to meet the actual requirement and realize reasonable utilization of resources. If the two sets of devices are set to be in the running state for the same interval if manual deployment is carried out, and if the issued result is not monitored, the running states of the two sets of devices at the same interval exist in the station at the moment, and the data uploading and the command issuing can be disordered, so that the reliability of the manual deployment can be improved by concentrating the manual deployment into the main control device, and meanwhile, the cooperativity of the manual deployment and the automatic deployment is ensured. A flowchart of manual deployment is shown in fig. 6, and specifically includes the following steps:
step 8.1, judging whether the manual work issues the state information through the operation and maintenance interface, if so, turning to the next step, and if not, turning to the step 8.1;
8.2, each device receives the state information issued by the operation and maintenance interface and sends the state information to the master control device;
step 8.3, the master control device receives the state information;
step 8.4, judging whether a deployment conflict exists, if so, adjusting a deployment mode, turning to the next step, and if not, turning to the next step;
8.5, the main control device issues a migration command;
step 8.6, the target device reads and stores the task table;
step 8.7, executing migration;
and 8.8, after the migration is finished, issuing a heartbeat message according to the new state, and turning to the step 8.1.
The main control device realizes the adjustment of manual deployment by considering the priority of the device and the reasonable configuration of resources, but the main control device is manually set as the main control device.
(1) In the two running states, the main control device preferentially considers manual deployment, and automatically sets the logic measurement and control of the original running state to be a hot standby state. Therefore, only one logic measurement and control function for realizing the interval exists.
(2) In a plurality of sets of measurement and control devices, for the same interval, the 'running' state is not set manually, but the 'hot standby' setting exists. At this time, the main control device automatically switches the hot standby state of the corresponding interval of the corresponding device into the running state so as to ensure that at least one running state exists in the interval.
(3) If all the intervals of the two sets of measurement and control devices are set to be in the 'running' state, the uniqueness of the 'running' state in the same interval and the reasonable distribution of resources are considered, and a plurality of 'running' states are evenly distributed in the two sets of devices at intervals, so that the burden of a single device is reduced, and the reasonable utilization of resources is realized.
(4) If in a plurality of sets of measurement and control devices, the hot standby state is not set manually for the same interval, but the cold standby state is set. The main control device automatically adjusts the cold standby state into the hot standby state so as to ensure the rapidity of the next automatic deployment.
Considering the operation of the 'hot standby' measurement and control program, for manual deployment, the processing modes of the management program and the measurement and control program during switching of different states are as follows:
(1) and (3) switching between the running state and the hot standby state, modifying the state of the interval by a management program of the device, and issuing by a monitoring program start-stop GOOSE.
(2) And the conversion between the states of cold standby or stop and running or hot standby is realized, the interval parameters and the measurement and control program are deployed by the management program, and the corresponding measurement and control program is started and stopped.
Because the 'running' state realizes the measurement and control function at intervals, manual online deployment is realized by modifying the device where the 'running' state is located manually, meanwhile, the logical measurement and control program of the 'hot standby' state starts the corresponding measurement and control program, the management program of the main control device can give priority to the logical measurement and control device of the 'hot standby' state during migration, and meanwhile, the state information of the cluster device is analyzed to determine the deployment strategy. Thus, the migration direction of the automated deployment is influenced manually by modifying the device in which the "hot standby" state resides. To limit the scope of the devices for automatic deployment or automatic deployment migration, the interval not participating in automatic deployment may be set to a "deactivated" state. At this time, the logic measurement and control in the 'off' state is not considered in the automatic deployment. Therefore, manual deployment and manual real-time control over automatic deployment thereof are simultaneously realized through state setting.
And 9, all devices send heartbeat messages in the current state.
In the embodiment, the state monitoring of each device and each interval is realized by operation and maintenance software instead of traditional liquid crystal, which is integrated in the background and supports independent deployment. For manual deployment and automatic deployment, the operation and maintenance software can refresh the state of each interval in real time, and the current state of each interval can be checked manually through the operation and maintenance software. Meanwhile, the states of all devices corresponding to intervals can be modified through the operation and maintenance interface, and manual online deployment is achieved.
In order to verify the feasibility and the rationality of the method, the measurement and control functions of a certain 110kV transformer substation are deployed. The substation requires 12 bays to be deployed in a cluster. And 3 sets of cluster measurement and control devices are configured in the station, and each set of device is provided with 12 measurement and control parameters at intervals, which correspond to 12 intervals of a 110kV circuit, each side of a main transformer, a 110kV bus, an inner bridge and the like. In the initial state setting, the 12-interval state of the apparatus 1 is set to "on", all the states of the apparatus 2 are set to "hot standby", and the apparatus 3 is set to "cold standby", taking into account the specific weight of the number of arrangement intervals.
The state of the interval is modified by the operation and maintenance software, and the second time and the third time in the table 1 are manually set in the first state. The setting results in table 1 show that, when the "running" state of the logical measurement and control of the device 1 is manually set as the "hot standby" state, and the "hot standby" state is not modified to the "running" state, two "hot standby" states exist for the same interval, and the "running" state does not exist. Because of the loss of the spaced running state, the master control device preferentially considers the manual deployment, and changes the hot standby state of the device 2 into the running state, thereby not only ensuring the uniqueness of the running state, but also ensuring the priority of the manual configuration. Meanwhile, when the 'hot standby' state does not exist in the manual setting, the manual setting is preferentially considered, and the 'cold standby' state of the device 3 is modified into the 'hot standby' state.
In table 2, after the second manual deployment is completed and the device 2 is abnormal, the device 3 is selected as the migration target device instead of migrating to the device 1. Therefore, when the device in the "hot standby" state is manually modified, the migration direction of the automatic deployment will also change. And for the same interval, except for the logic measurement and control in the 'running' state, the rest are 'inactive', and at the moment, the logic measurement and control in the 'running' state is abnormal, and the migration cannot occur.
