Embodiment 1
[0063] Figure 4 It is a structural diagram of a ring-closing power-swapping measurement and control system provided in an embodiment of the present application.
[0064] Such as Figure 4 As shown, the closed-loop power swap measurement and control system provided in this embodiment includes a power grid parameter detection module, a switching value detection module, a processor, a communication interface and a closed-loop control module. The processor is respectively connected with the grid parameter detection module, the switch value detection module, the communication interface and the loop closing control module.
[0065] The power grid parameter detection module is used to detect the power grid parameters of the power grid of the substation configured with three loop closing ports. The grid parameters include the bus voltage at one end of the grid, the bus voltage at the second section, the substation voltage at No. 1 station, the substation voltage at No. 2 station, t...
Embodiment 2
[0082] Image 6 It is a structural diagram of a ring-closing power-swapping measurement and control system provided by another embodiment of the present application.
[0083] Such as Image 6 As shown, the present embodiment adds a display device, a keyboard and a plurality of indicator lights 20 respectively connected to the processor on the basis of the previous embodiment.
[0084] The display device is used for displaying the state of the loop closing circuit breaker, the voltage of the first-stage busbar, the voltage of the second-stage busbar, and the voltage difference and phase difference between the buses.
[0085] The keyboard is used to receive the instructions of the controller on the spot and output the ring closing command, which is used as the control terminal of the local ring closing operation.
[0086] The display device is preferably a liquid crystal touch screen, and can also integrate the above-mentioned keyboard.
[0087] A plurality of indicator light...
