receiving a scheduled transfer load instruction to perform transfer load preset mode selection, performing transfer load system mode selection according to the acquired data information, and issuing a loop closing instruction of the loop closing circuit breaker through a switching value output logic unit when the received preset mode is consistent with the system mode selection;
the logic analysis judgment is carried out on the data information fed back by the loop closing circuit breaker, and the logic analysis judgment is used for confirming whether the loop closing operation is successfully completed or not: if the loop closing operation is successful, issuing a loop opening instruction of the loop opening circuit breaker through the switching value output logic unit;
logic analysis judgment is carried out on the data information fed back by the loop-opening circuit breaker, and the logic analysis judgment is used for confirming whether loop-opening operation is successfully completed or not: if the ring-opening operation is successful, the load transferring operation is completed;
if the ring-opening operation fails, performing remedial measure logic analysis and judgment, including:
if the loop closing current is greater than the current splitting action fixed value and the loop closing time is greater than the current splitting time fixed value, judging that the repairing condition is met;
if the loop closing current does not reach the current splitting action fixed value or the loop closing time is smaller than the current splitting time fixed value, judging that the repairing condition is not met;
when the remedying condition is met, a remedying measure instruction is issued, and when the position signal of the un-operated loop-opening breaker is switched from on to off, the load transferring operation is completed;
when the remedy condition is not satisfied, judging a recovery time interval of successful ring closing operation and failure of ring opening operation:
when the recovery time interval of successful ring closing operation and failure ring opening operation reaches a preset condition, the circuit breaker is operated manually;
and when the recovery time interval for successful ring closing operation and failed ring opening operation does not reach the preset condition, continuously monitoring the data information until the remedial condition is met.
2. The method for controlling an intelligent ring opening and closing operation according to claim 1, wherein the logic analysis and judgment of the data information fed back by the ring closing circuit breaker is used for confirming whether the ring opening and closing operation is successfully completed, and the method comprises the following steps:
when the data information fed back by the loop closing circuit breaker is consistent with the data information judged by the loop closing logic and the loop closing incoming line current is not found and the loop closing circuit breaker position signal is found, judging that the loop closing operation is successful;
and when the data information fed back by the loop closing circuit breaker is inconsistent with the data information judged by the loop closing logic, or the loop closing incoming line current is still not available, or the loop closing circuit breaker position signal is still in the split position, judging that the loop closing operation fails.
3. The method for controlling an intelligent loop opening/closing operation according to claim 1, wherein the logic analysis and judgment of the data information fed back by the loop opening/closing circuit breaker is used for confirming whether the loop opening operation is successfully completed, and the method comprises the following steps:
when the data information fed back by the loop opening circuit breaker is consistent with the data information judged by the loop opening logic, and the loop opening incoming line current is switched on or off from the position signal of the loop opening circuit breaker to the time-sharing state, judging that the loop opening operation is successful;
and judging that the loop opening operation fails when the data information fed back by the loop opening circuit breaker is inconsistent with the data information judged by logic or the loop opening incoming line current still exists or the loop opening circuit breaker position signal still is at the closing position.
