Abstract

The invention provides a secondary equipment time monitoring management system and method for a power system. The system comprises a time synchronization device, a time synchronization monitoring device, an in-station communication management unit, a dispatching master station, a station layer network switch and at least one monitoring subsystem; the monitoring subsystem comprises a time synchronization monitoring signal generator and at least one secondary electric power equipment. The method comprises the following steps: constructing a time monitoring management system, initializing a parameter, generating a monitoring signal, responding to the monitoring signal, calculating a time deviation value, and performing alarm judgment and remote transmission. The secondary equipment time monitoring management system and method for the power system provided by the invention can realize the remote monitoring of time synchronization of the secondary electric power equipment, give the alarm when exceeding a set threshold and have a better application prospect.

Description

technical field [0001] The invention relates to a system and method for monitoring and managing secondary equipment in a power system, in particular to a system and method for monitoring and managing the time of secondary equipment in a power system. Background technique [0002] In order to implement the "State Grid Corporation's 2014 Dispatching and Control Key Work Task Arrangement" (Tiao Zong [2014] No. 17) and the "Notice of the State Research and Development Center on Strengthening the Time Synchronization Operation Management of Power Systems" (Tiao Zi [2013] No. 82) Requirements, the National Research Center issued [2014] No. 53 document, the notice on strengthening the time synchronization monitoring and management of the power system. [0003] Power system time synchronization monitoring follows the principle of hierarchical management. Dispatch control centers at all levels monitor and manage the time synchronization status of direct dispatching plants and sub-dis...
