Embodiment
A kind of improved power distribution automation implementation method disclosed by the invention, the DAS substation need not dispose " three is distant " module (a configuration communication module, power module etc.) in the transformer station, " three is distant " module that DAS uses the RTU of SCADA system realizes power distribution automation, RTU and SCADA main website and DAS substation all communicate, the instruction RTU that both send will carry out, and the inventive method is specific as follows:
DAS remote measurement, remote signalling step: the RTU of SCADA system to the DAS substation, is shown the information uploading gathered with this information uploading by the DAS substation again to the DAS main website and on the DAS work station;
SCADA remote measurement, remote signalling step: the RTU of SCADA system shows the information uploading of gathering to the SCADA main website and on the SCADA work station;
DAS remote control step: the DAS work station transfers to the DAS main website with remote control command, by the DAS main website this instruction is transferred to the DAS substation then, by the DAS substation this instruction is transferred to the RTU of SCADA system again, carries out this instruction by RTU;
SCADA remote control step: the SCADA work station transfers to the SCADA main website with remote control command, by the SCADA main website this instruction is transferred to the RTU of SCADA system again, carries out this instruction by RTU.
The essence of the inventive method is RTU " one receive two ", uploads to 2 main websites during the information of same of collection; Simultaneously RTU also is 2 bottom executive components that system is common, thus require 2 main websites to be sent to the instruction of RTU necessarily can not be conflicting.Because the 10kV of transformer station outlet, the 10kV looped network station of domestic application DAS all belong to district's accent (county's accent, auxiliary tone) compass of competency at present, and DAS work station and SCADA work station all place same district key degree indoor, therefore, dispatcher's " remote control " in SCADA and two systems of DAS inconsistent phenomenon (unless dispatcher's human error) of issuing an order can not occur, thereby guarantee that 2 systems send the consistency of instruction to RTU.
