Description
Technical field
The present invention relates to the AC power supervising device of AC power monitoring fields of measurement, more particularly to a kind of transformer station.
Background technology
For a long time, in transformer station, monitoring system or substation management are attention high pressure, to low pressure（380V systems）
And think little of, existing technical scheme is：
1st, using single mother partition power supply mode of the old-fashioned mother of two inlet wire one, when normal, each self-operating of two inlet wires, one
When road inlet wire has a power failure or overhauled, bus need to be closed.The program is operated using automatic or manual, even if using automatic behaviour
Make, its response time is more at 2 ~ 3 seconds, causes power off time longer, the control, protection equipment to transformer station can cause certain
Influence.
2nd, at present, more use double loop power supply inlet wire makees inlet wire switching device, but make using PC grades of ATS twin-power switch
With traditional controller.Using the program, switching time substantially reduces, and can accomplish in 100mS, but due to using traditional control
Device processed, general controller only has single control model, it is necessary to determine active and standby inlet wire in wiring, and operational flexibility drops significantly
It is low, and communication function is weaker, the data volume of collection is small.If the demand of digital transformer substation need to be met, it is necessary to increase by one it is comprehensive
Electric quantity collector, switch acquisition device are closed, equipment increases.For the transformer station using IEC61850 communication standards, the party
Case needs to increase more communication apparatus to meet requirement.
The content of the invention

Further, described switching value output module includes closing the first lead-in circuit breaker contact, closes the open circuit of the second inlet wire
Device contact, point the first lead-in circuit breaker contact, point the second lead-in circuit breaker contact, alarm contact.
Further, prepared auto restart is set to control prepared auto restart control in output module, processor in described core processor
Switching input module that output module is monitored according to processor, analogue collection module collection data control switch amount it is defeated
Go out module.
The advantage of the invention is that：1st, can because transformer station's power supply employs PC grades of ATS twin-power switch as main inlet wire
The advantage of ATS twin-power switch automatic switchover is given full play to, its most fast switching time is 100mS, much smaller than original technical side
Case.
2nd, as a result of STM32F103VCT6 embedded microcontrollers as core processor, two-way electricity can be monitored
The state in source, bus power supply status, bus current, 30 way switch amount input states, 16 way switch amounts of output, 3 road ATS logic controls
System output, this complete with monitoring analog quantity compared with common Double-power controller, controlling switch amount input and output quantity
Many, ATS twin-power switch control models are more complete, can meet various types of user's requests.
3rd, as a result of STM32F103VCT6 embedded microcontrollers as core processor, can easily it realize
It is locally displayed and communication module, particularly realizes the requirement that IEC61850 communications protocol is used in digital transformer substation.
