Transition method of intellectualized monitoring system modification process of conventional transformer substation

Abstract

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.

Description

technical field [0001] The invention belongs to the field of power transformation and distribution, and in particular relates to an intelligent transformation method for conventional substations. Background technique [0002] Substations using traditional transformers and secondary equipment are usually called conventional substations. [0003] Correspondingly, intelligent equipment is used, with the basic requirements of digitization of information of the whole station, networking of communication platform, and standardization of information sharing, to automatically complete basic functions such as information collection, measurement, control, protection, measurement, and monitoring, and to support power grids as needed Substations with advanced functions such as real-time automatic control, intelligent adjustment, online analysis and decision-making, and collaborative interaction, which realize interaction with adjacent substations and grid dispatching, are called smart s...

Problems solved by technology

[0012] Because the network equipment of 103 protocol communication (adopting point-oriented technology) and the network equipment of 61850 protocol communication (adopting object-oriented technology) cannot communicate directly with each other due to the inconsistency of the communication protocol, some measurement and control devices related to interlocking cannot exchange each other Therefore, in the process of intelligent transformation of substations, the measurement and control devices at the bay level cannot achieve perfect logic blocking, which largely affects the continuous safe operation of substations and the smooth implementation of intelligent transformation of existing conventional substations
