Embodiment Construction
[0022] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.
[0023] The network structure of the remote control safety measure implementation method of the relay protection device is as follows: figure 1 and 2 As shown, the monitoring background, protection management machine, and telecontrol host are all executive devices for remote remote control of relay protection devices. exist figure 2 Among them, for the intelligent station, the remote control host and the monitoring background are independent, and each can complete the remote control work independently. exist figure 1 Among them, for conventional stations, the remote control work that needs to be completed by the remote control host and the monitoring background should be completed through the final execution of the protection management machine (using the IEC60870-5-103 protocol). The program software completes the updating and synchronizin...

The present invention provides a remote control security measures execution method for a relay protection device. The method comprises the following steps of S1, providing an allowable list, and automatically synchronizing the information of a relay protection device to an executing device used for remotely controlling the relay protection device and arranged in a transformer substation, wherein the allowable list includes the information of the relay protection device capable of being remotely controlled; S2, after receiving a remote control instruction by the executing device, judging whether to permit the operation or not: firstly, accessing the allowable list; secondly, searching and judging whether an instruction executing device is in the allowable range or not according to the information of the relay protection device of the remote control instruction; if the device is in the allowable range, executing the remote control instruction; otherwise, refusing to execute the remote control instruction and feeding back an illegal operation alarm. According to the invention, the remote control of the relay protection, in joint debugging with the security measures, is realized. The joint debugging of the security measures isolation is conducted independent of the relay protection device through the allowable list. Therefore, the execution of the security measures is realized.
Description
technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to the implementation of safety measures for remote remote control of a conventional substation based on the IEC60870-5-103 protocol and an intelligent substation relay protection device based on the IEC61850 protocol. Background technique [0002] With the development of intelligent stations and the continuous deepening of the application of unattended substations, research on the promotion and application of remote operation of relay protection devices has been carried out in China. Mainly include: remote control joint commissioning of relay protection device remote investment and withdrawal of soft pressure plate (referred to as “relay protection remote joint commissioning”), research on the implementation of safety measures for relay protection remote investment and withdrawal of soft pressure plate, etc. This program focuses on the research on the implementati...
