Description

A kind of transformer substation communication power supply monitoring system and method

Technical field

The present invention relates to communication power supply monitoring field, more particularly to a kind of transformer substation communication power supply monitoring system and method.

Background technology

At present, power network schedule automation is highly developed perfect, and increasing transformer station realizes unattended.But After personnel withdraw, the safe operation of transformer station becomes abnormal important, and the demand for security monitoring is more and more stronger.Although power network Dispatch automated system covers the information of section communication power-supply system, but most of communication equipment operation conditions can not be slapped completely Hold.

In transformer station, communication power supply is responsible for scheduling switch, communication wiring frame, electric wave carrier into transformer station etc. Communicate load and power supply is provided, be to ensure one of important composition that transformer station normally runs.At present, transformer station to digitlization, nobody The direction of type on duty and networking centralized management is developed, and various electrical equipments gradually realize remote monitoring, but for communication The remote on-line monitoring of power supply is but without perfect embodiment；Therefore the operation conditions of communication system can not comprehensively be reflected, it is special It is not that dispatch automated system can not detect malfunction, be unfavorable for communication when operation exception initial stage occurs in communication system The real-time monitoring of power-supply system and whole network system.

Existing transformer substation communication power-supply system operationally, is primarily present problems with：

1st, the configuration of the man-machine interface of existing communication apparatus for monitoring power supply and transformer station, layout, wiring are a kind of close couplings Pattern, each transformer station is required for individually developing a set of man-machine interface, it is impossible to which according to the requirement of transformer station, flexibly displaying is each The man-machine interface information of transformer station, software portability is poor, is unfavorable for centralized Control and digital quantity communication, it is impossible to effective to realize Human-computer dialogue, can not arbitrarily change operational factor in operation.

2nd, current transformer substation communication power-supply device is built using 61850 model files of IEC 61850-7-420 standard implementations Mould, IEC61850-7-420 standards do not list the extension class of correlation to the logical node of transformer substation communication power-supply device.From DL/ After the standards of T 860 are released, original modeling method can not meet the regulation of existing standard, not meet state's net tender standard.It is former Some model files create different logical node LN (logical node, hereinafter referred to as LN) due to different producers, mutually behaviour The property made is poor.

61850 model files are completed by the way of manual editing always, manual editing IED performances description (IED Capability Description, hereinafter referred to as ICD) file is high to the technical requirements of engineering staff, and workload is big, easily goes out It is wrong.If, it is necessary to update IED performance profiles after configuration modification.Wherein, IED is Intelligent Electronic Device, hereinafter referred to as IED.

3rd, due to the communication power device of different manufacturers exist it is technical disconnect it is uncoordinated, with the demand of systems soft ware Addition, measuring point increase, not may result in the software version of the software version of the power supply system for communications and other power-supply systems not Matching, equipment can not normally be run, especially for intelligent substation and unattended power station, be influenceed bigger.

4th, the communication mechanism of current Communication Power Equipment is first artificial manual configuration port information, then preserves parameter and restarts Come into force.If slave computer changes other kinds of equipment and needs to remodify configuration, then preservation parameter, which is restarted, comes into force.It is this to match somebody with somebody Put modification and-preserve-technical requirements height of the mechanism restarted to operating personnel, flexibility, poor compatibility.
