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

Abstract

The utility model provides a transition method of an intellectualized monitoring system modification process of a conventional transformer substation and belongs to the field of power transformation and distribution. A bus 61850 protocol measuring and controlling device is first modified, replaces an original bus measuring and controlling device and is connected to a 61850 protocol intellectual station level network to achieve a separating layer logic locking function measured and controlled by a bus and be responsible for remote operation of a bus earthing knife-switch. The original bus measuring and controlling device is not dismantled, a remote operation function of the device is forbidden, and improvement of the separating layer logic locking function of an original 103 protocol network side switch is guaranteed. The separating layer logic locking function related with the bus measuring and controlling device in the 61850 protocol intellectual station level network is forbidden, and the integrity of the bus disconnecting switch locking function can be ensured by means of the logic locking function of a stable level. Original 103 protocol measuring and controlling devices are gradually modified in sequence according to a power outage plan, the bus separating layer logic locking function of the 61850 protocol intellectual station level network is recovered after all of modification is finished, the integrity of full-station separating layer locking is achieved, and the original 103 protocol bus measuring and controlling devices are dismantled. The transition method can be widely applied to the intellectualized modification field of the conventional transformer substation.

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
