PRS-3342 distributed intelligent station/substation terminals independently developed by CYG ET adopt modular design and undertake the functions of fault detection, information transmission, control command acceptance and execution. The common unit supports edge computing, which can realize data collection and local high-speed processing at the station/substation. The bay unit supports the dual main protection of 5G-based longitudinal differential and longitudinal current and a variety of intelligent FA modes, and creates an intelligent "end" layer deployment with intelligent sensing and online monitoring equipment to realize holographic sensing in the station/substation area; It can realize on-line monitoring, condition-based maintenance, power collection and control of primary equipment, detect faults, locate and isolate fault areas and restore power supply in non-fault areas, thus improving power supply reliability.
Distributed Intelligent Station/Substation Terminal Series
It is mainly used in 10kV outgoing line of substations, and ring main units, switching stations and box-type substations in distribution network.
Product Overview
Product advantages
-
High sensitivity and high speed dynamic multi-redundancy protection strategy
The dual main protection solution supports phasor and transient differential protection positioning technology of the whole line, realizing full short circuit/grounding coverage; It can flexibly adapt to the change of line topology, adapt to various grid racks and distributed energy access, improve the accuracy of fault location in distribution network, do not need differential cooperation, and isolate faults in the region in milliseconds -
Optimal selection in intelligent power supply recovery
It can calculate the load to be transferred based on the load memory; According to the requirements of real-time capacity margin and operation mode of each contact power supply, it can automatically switch on the best contact power supply, reduce the power outage range in non-fault areas, and resume power in seconds -
Economical and rapid deployment based on wireless network mode
5G communication replaces optical fiber, without considering external factors such as optical fiber corridor. The channel resources are rich, which can be connected as needed, and the construction period is short, which is more conducive to implementation and promotion; For 5G communication, users just need to carry out the operation & maintenance of 5G communication equipment at the substation, effectively reducing operation and maintenance costs and improving efficiency; 5G construction also meets the needs of new national infrastructure
