Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
The invention discloses a service subscription mode-based data transmission method between main and distribution network systems, which realizes the automatic transmission of real-time data of 10kV equipment between the main and distribution network systems, and is shown in figure 1, and the method comprises the following steps:
the first step is as follows: establishing data transmission service association between a main network power dispatching automation system (called a main network system for short) and a distribution network power dispatching automation system (called a distribution network system for short) according to the requirements of GB/T33602 and 2017 power system general service protocols, wherein the main network system side is a data transmission service end, and the distribution network system side is a data transmission client;
the second step is that: the distribution network power dispatching automation system screens all 10kV equipment according to the voltage grade of the equipment of the system, and then writes the telemetering, remote signaling and remote control measuring point information associated with the equipment into a subscription request data list file, wherein the file comprises a data type, a sequence number, a measuring point name and a distribution network side measuring point ID, and the data type, the sequence number, the measuring point name and the distribution network side measuring point ID are as follows: the measuring point name meets the requirements of the naming specification of the DL/T1171 and 2012 power grid equipment general data model;
the third step: the data transmission client of the distribution network system sends a subscription request data list file to the data transmission server of the main network system;
the fourth step: after receiving the subscription request data list file, the data transmission service end of the main network system matches telemetering, remote signaling and remote control measuring points associated with 10kV equipment in the system according to measuring point names in the file to obtain a mapping relation between measuring point IDs on the main network side and measuring point IDs on the distribution network side, and writes the measuring point information passing the matching into a subscription confirmation data list file, wherein the file comprises data types, sequence numbers, measuring point names, the measuring point IDs on the distribution network side, the measuring point IDs on the main network side and the measuring point information not passing the matching are also written into the subscription confirmation data list file, and the measuring point IDs on the main network side are written into NULL;
the fifth step: the main network system data transmission server returns a subscription confirmation data list file to the distribution network system data transmission client to complete a data subscription process;
and a sixth step: the main network system data transmission server side receives real-time data sent by a plant station side and acquired by the main network data acquisition function in real time, and packages and sends the real-time data to the distribution network system data transmission client side through a power system universal service protocol according to main network side measuring point IDs in a subscription confirmation data list file;
the seventh step: after receiving the real-time data issued by the main network system data transmission server, the distribution network system data transmission client confirms the mapping relation between the main network side measuring point ID and the distribution network side measuring point ID in the data list file according to the subscription, converts the mapping relation into a distribution network side measuring point ID and a measuring point value, and sends the distribution network side measuring point ID and the measuring point value to the data monitoring function of the distribution network system to complete the real-time operation monitoring of the distribution network.
Eighth step: when the distribution network system needs to remotely control 10kV equipment of a plant station to which the main network system belongs, the distribution network remote control function software converts a remote control command into a main network system remote control measuring point ID and a remote control value through a distribution network system data transmission client and sends the main network system remote control measuring point ID and the remote control value to a main network system data transmission server;
the ninth step: after receiving the network distribution side remote control command request, the main network system data transmission server calls corresponding security check, and if the remote control command is passed through the check, the main network system data transmission server issues the remote control command to the station to which the remote control equipment belongs, otherwise, the main network system data transmission server does not send the remote control command, and returns a check result to the network distribution system data transmission client;
the remote control safety check of the data transmission server side of the main network system comprises the following steps: whether the equipment needing to be remotely controlled is allowed to be controlled by the distribution network system or not and whether the voltage grade of the equipment needing to be remotely controlled is 10kV or not. If yes, the safety check is passed, and if not, the safety check is failed.
The tenth step: and the distribution network remote control function software receives a remote control checking result forwarded by the distribution network system data transmission client, if the checking is correct, the real-time data sent by the main network system are continuously received, and after the state of the remotely controlled 10kV equipment is changed, the remote control process is ended.
After the model of the distribution network system is changed, if the configuration of the required 10kV data is changed, the data subscription is directly carried out again from the second step to the fifth step without disconnecting the service association with the main network system, and then the main network and the distribution network system are processed from the sixth step to the tenth step.
Data acquisition of 10kV equipment at a plant station end is completed by a main network system, so that modification of a 10kV equipment model is also performed before a distribution network system by the main network system, in the main and distribution network power dispatching automation system, unique identification IDs of the equipment and a measuring point are not allowed to be reused, and an existing ID is not changed to another equipment or measuring point. Therefore, in the 10kV equipment model modification process, the condition that related data are disordered does not occur.
The method can realize that the distribution network system automatically acquires the required real-time data of the 10kV equipment in a service subscription/release mode under the condition that the manual maintenance of data transmission configuration does not exist between the main distribution network system and the distribution network system, effectively reduces the workload of maintenance personnel, and improves the accuracy and the real-time performance of the data of the distribution network system.
