Description

A kind of transformer station station is with the online early warning system of alternating current-direct current integration power-supply system
Technical field
The present invention relates to a kind of transformer station station with the online early warning system of alternating current-direct current integration power-supply system.
Background technology
Transformer station's station power source system of electric system is the general name of transformer station with confession distribution and power conversion equipment, mainly contains AC power, direct current operative power source, accumulator and UPS in low-pressure side.For monitoring and the management of transformer station station with power supply, each power-supply system has all been uploaded a batch data, and there are several shortcomings in the data of transmitting now:
(1) data of transmitting are machinery relatively, does not have the analysis between data.
(2) some important incident or fault, data and information are meticulous inadequately.
(3) belong to information afterwards basically for alarm, fault, promptly after the prompting of alarm and fault occurring, produced adverse consequences.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of transformer station station with the online early warning system of alternating current-direct current integration power-supply system.
The solution of above-mentioned technical matters, the technical scheme that the present invention adopts is following:
A kind of transformer station station is with the online early warning system of alternating current-direct current integration power-supply system; Comprise online early-warning apparatus (1), it is characterized in that: described online early-warning apparatus (1) links to each other with AC power monitoring module (3), direct supply monitoring module (4), ups power monitoring module (5) and communication power supply monitoring module (6) respectively through Ethernet switch (2).
Described AC power monitoring module (3) is connected communication with the interchange intelligent controller of AC power with intelligent AC feeder line module through the RS485 bus respectively; Exchange the intelligent controller monitoring and exchange inlet wire and automatic control function, intelligent AC feeder line module monitors exchanges feeder line and opens state and current data.
Described interchange intelligent controller has 2, intelligent AC feeder line module to have 4.
Described direct supply monitoring module (4) is connected communication through the RS485 bus with two direct-current supervision modules of direct supply respectively, and described direct-current supervision module connects D.C. isolation monitoring device, feeder line isolating switch collecting unit, charging module and the accumulator checking device of this section straight-flow system respectively.
Described ups power monitoring module (5) is connected communication with the inversion module of ups power system with inversion feeder line monitoring modular through the RS485 bus respectively, and the inversion module correspondence is input as AC power and direct supply, is output as AC power.
Described communication power supply monitoring module (6) is connected communication with the DCDC module of the power supply system for communications with communication feeder line monitoring modular through the RS485 bus respectively.
Principle of work:
Online early warning system is obtained the data such as remote signalling, remote measurement, definite value of each power-supply system on the one hand through the RS485 Bus Real Time; On the other hand; In the device parameter Input Online early warning system of user with the alternating current-direct current integration power-supply system; Like parameters such as charging set specifications and models, service life of equipment, each switch rated current, online early warning system forms an analog power system with the practical power systems compliant according to the information of this two aspect.The analog power system in conjunction with the data of obtaining in real time, carries out data analysis, and significant data is stored according to the best power operating mode operation of this configuration, like busbar voltage, insulation ground connection information, accumulator data etc.
Online early warning system is carried out according to definite value detection, real time data analysis, working specification monitoring, detection equipment life, important parameter historical data analysis by certain strategy circularly in proper order; If in a certain, find actual inconsistent with the optimum operation data; Then carry out early warning; And propose to handle suggestion, sound and light alarm is sent in this locality, simultaneously early warning information is reached remote monitoring through 61850 and knows the user.After user's site disposal was normal, the early warning content disappeared, and signal recovers, and this record is deposited in the historical record.
Beneficial effect: the present invention can be before accident takes place; Through the unusual sign of some data variation; What event may take place in prediction; Remind the user before accident takes place, to handle early, prevent avoidable accident to take place, guarantee that alternating current-direct current integration power-supply system ground provides highly reliable and high-quality power supply for substation equipment.
