Description
Technical field
The present invention relates to power quality engineering device technique fields more particularly to a kind of agriculture city net platform to become comprehensive electric energy quality management
System and management method.
Background technology
In the power system, taiwan area refers to the supply district or region of (one) transformer.Distribute-electricity transformer district refers to power distribution network
The supply district of middle transformer.Caused by matching electricity demanding, the network distribution transformer (hereinafter referred to as distribution transforming) of domestic 10kV to 400V
It is distributed in each position in the whole nation, the construction criteria of each area distribute-electricity transformer district has differences, and makes the kind of distribute-electricity transformer district installation equipment
Class and quantity are different, and some distribute-electricity transformer districts are distributed in the poor ground such as transportation condition, site environment, artificial protective awareness
Area needs continuous if making each network distribution transformer for being responsible for O&M that can reach the operating index of State Grid Corporation of China's requirement
Increase operation maintenance personnel, but since bankroll problem which is infeasible.And even if everyone be responsible for safeguard a transformer, but due to
The variability of power distribution network power load and electrical equipment can not continuously monitor for 24 hours, and equipment failure rate can only be made to reduce and power
Quality improves, it is difficult to accomplish the long-term failure-free operation of controller switching equipment.
Currently, two aspects still mainly concentrated in distribution automation both at home and abroad:10kV and the above distribution, terminal user
Ammeter centralized measure, specially negative control system has been brought in change into 10kV, 10kV public affairs become and end loads are included in electricity centralized meter-reading system.But
It is, for being distributed most wide and the most complicated 0.4kV distribution lines and high-end user group and for the comprehensive of low-voltage distributing line
In terms of protection, comprehensive automation and cluster optimum management, all there are no correlative studys both at home and abroad, and also all good means do not carry out
Comprehensive automation management.This part distribution line is often easiest to break down and main link occurs for line loss.Traditional
Both ends automatic mode is very easy to ignore the incipient fault with network operation, and once breaks down and be not easy fast quick-recovery.
Secondly, distribution transformer is the capital equipment of low-voltage network, and construction dosage is huge in low-voltage distribution system,
The economic benefit of operation directly influences the economic benefit of entire electric system.In town and country 10kV and power distribution network below, match
The loss of piezoelectric transformer accounts for about the one third of line loss, and the loss of rural power distribution transformer accounts for entire electric system damage
60% or so of consumption.
Again, due to scene practical problem such as site environment it is changeable, equipment fault takes place frequently, artificial destruction, power quality
The reasons such as poor make distribute-electricity transformer district power supply be difficult to realize safe and stable, efficient electrical energy transportation.
Therefore, in current low-voltage distribution transformer platform district, each distribute-electricity transformer district is in isolated operation state, operation maintenance personnel work
Amount is big, and management cost is larger.
