TRANSITION METHOD FOR MONITORING SYSTEM MODIFICATION PROCESS DURING INTELLIGENT MODIFICATION OF CONVENTIONAL SUBSTATION |
摘要 |
<p>Provided is a transition method for a monitoring system modification process during intelligent modification of a conventional substation. The method comprises: modifying a 61850 protocol measurement and control device of a bus first, replacing an original bus measurement and control device, and accessing a 61850 protocol intelligent station control level network so as to achieve a spacer-layer logic locking function measured and controlled by the bus and responsible for a remote control operation of an earthing knife switch of the bus; not dismantling the original bus measurement and control device, forbidding a remote control operation function thereof, and guaranteeing the improvement of the spacer-layer logic locking function of an original 103 protocol network side switch; suspending the spacer-layer interlocking function related to the bus measurement and control device in the 61850 protocol intelligent station control level network, and guaranteeing the integrity of a bus disconnecting switch locking function by means of a logic locking function of the station control level; and modifying the original 103 protocol measurement and control devices successively according to strings based on a power outage plan, recovering the bus spacer-layer interlocking function of the 61850 protocol intelligent station control level network after all the modification is finished, achieving the integrity of full-station spacer-layer interlocking, and dismantling the original 103 protocol bus measurement and control devices. The method can be widely used in the field of intelligent modification of conventional substations.</p> |
