| Abstract: | With small power supply system connected, the distribution system has developed from the traditional sim- ple single-source radial-network to a complicated multi-source network. The connected way to the earth of the termi- nal transformer, relay protection and automation device are affected. Based on the relevant procedures and the analy- sis of possible system failure,this paper disscused how the synchronized small power source affected the relevant pro- tection and automation device, and proposed a reasonable allocation plans for secondary equipment. Practice has proved that the plan will ensure the safety and stability of power system as well as small power supply system. |
| Keywords: | small power supply system integration into the power networks stepout relay protection automation device |
