| 總結: | Power system includes many variety of equipment. A lot more amount of circuit breakers and relays are necessary to protect the system. The relays in the power system should be coordinated correctly so as to prevent mal-operation and therefore to avoid the unneeded outage of healthy section of the system. The overcurrent relays are usually the foremost protection product in a distribution system. Overcurrent relay is typically used as backup protection. But in a number of situations it may become the only protection supplied. A relay should get sufficient possibility to protect the area under its main protection. Just if the main protection does not clean the fault, the actual back-up Protection must start tripping, and as a result, overcurrent relay coordination in power distribution system is a important issue of protection engineer. The overcurrent relay coordination in ring fed distribution systems is a very constrained optimization trouble. The purpose is usually to discover an optimum relay setting to minimize the time of interruption of the power source and to stay away from the mal-operation of relay. This research talks about linear programming technique for optimum coordination of overcurrent relays in a ring fed distribution system. |
