Described interchange intelligent controller has 2, intelligent AC feed line module to have 4.
Described direct supply monitoring module (4) is connected communication by the RS485 bus with two direct-current supervision modules of direct supply respectively, and described direct-current supervision module connects respectively D.C. isolation monitoring device, feeder breaker collecting unit, charging module and the accumulator checking device of this section straight-flow system.
Described ups power monitoring module (5) is connected communication with the inversion module of ups power system with inversion feeder line monitoring modular by 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 by the RS485 bus respectively.
Principle of work:
Online early warning system is the data such as the remote signalling by each power-supply system of RS485 bus Real-time Obtaining, remote measurement, definite value on the one hand, on the other hand, in the device parameter Input Online early warning system of user with the AC/DC integrated power-supply system, such as 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 Real-time Obtaining, carries out data analysis, and significant data is stored according to the best power operating mode operation of this configuration, such as busbar voltage, insulation ground connection information, accumulator data etc.
Online early warning system is sequentially carried out according to setting examination, real-time data analysis, working specification monitoring, detection equipment life, important parameter historical data analysis circularly by certain strategy, if in a certain, find actual inconsistent with the optimum operation data, then carry out early warning, and suggestion is processed in proposition, sound and light alarm is sent in this locality, simultaneously early warning information is reached remote monitoring by 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 utility model can be before accident occurs, by the unusual sign of some data variation, what event may occur in prediction, reminding user is processed before accident occurs early, prevent avoidable accident to occur, guarantee that AC/DC integrated power-supply system ground provides highly reliable and high-quality power supply for substation equipment.
