<p>A distributed spare automatic switching apparatus, especially a distributed spare automatic switching apparatus used for a power grid, provides a good technical guarantee for a wide-range application of connecting a distributed power supply system to a large power grid. The following steps are comprised: 1) connecting a circuit breaker position reflecting a distributed power supply to the spare automatic switching apparatus in parallel, wherein input of the circuit breaker position is obtained from a normally closed contact of the spare automatic switching apparatus; and 2) from two pairs of normally closed contacts that can reflect real-time power generation status of the distributed power supply in each line, connecting one pair to a judging loop of the circuit breaker position in the spare automatic switching apparatus in series, and connecting the other pair of the normally closed contacts to a corresponding continuous switching trip loop in the spare automatic switching apparatus in series. Connecting distributed power supply lines to an electric power system continuously is completed intelligently, in real time, accurately and without manual intervention. This can not only save operation costs for an electric power enterprise, but also reduce risks to secure and stable running of a power grid.</p> |
