The invention discloses a method for automatically switching stable control strategies based on warning signals of synchronous digital hierarchy (SDH) equipment, and belongs to the technical field of a power system and automation thereof. According to the method, the warning signals of the SDH equipment are accessed into a stable control device; the stable control device can acquire dynamic real-time information of multiple channels, which are communicated with the stable control device, after the warning signals of the SDH equipment are accessed into the stable control device, namely can analyze the combination of the warning signals of the SDH equipment in a real-time manner according to the relevant regulations of stable control service on communication code error, interruption and delay so as to judge whether the channels are in available states. Through the adoption of the method, the defect that the control measures of part of the stable control strategies cannot be executed reliably after the channels are in failure is avoided, and the reliability of a regional security control system is improved substantially.
Description
technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof. More precisely, the invention relates to an automatic switching method of a stability control strategy based on an alarm signal of a synchronous digital system device. Background technique [0002] In the regional stability control system (that is, the regional security control system), optical fiber is generally used for communication between stations. The typical inter-station communication mode between station A and station B is: station A stability control device<-->2M multiplexed communication interface equipment<- ->Synchronous Digital Hierarchy (Synchronous Digital Hierarchy, hereinafter referred to as SDH) equipment of station A <----optical fiber----->SDH equipment of station B<-->2M multiplexing communication interface equipment<-->B Stand still on the control device. That is, the stability control device will communic...
