| Abstract: | The paper analyzes how the DC/DC communication power(particular for power system) is connected to DC bus directly, and the problem when feeder switch short circuit occurs,it will not trip reliablely due to its own protection of DC/DC. The result verifies the mechnism when the problem occurs and the effectiveness to slove it by adding electrolysis electric capacity in the terminal of DC/DC bus. |
