Embodiment Construction
[0047] The channel switching method of the voltage and reactive power automatic control system provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] Such as Figure 6 As shown, the channel switching method of the voltage and reactive power automatic control system provided by the present invention includes the following steps executed in sequence:
[0049] Step 1. The S01 stage of normal system operation: Under normal circumstances, the substation participating in the AVC full-network joint commissioning of the local AVC system is running in the state of remote AVC joint commissioning, and its general joint commissioning settings and branch joint commissioning settings Both execute the remote strategy;
[0050] Step 2. The S02 stage of the scan cycle: it is the scan cycle when the local AVC system is running normally. Through scanning, channel abnormalities can be found in time and ...
