| Transmission line is the backbone of power grid, which is essential in power transportation, By so far, transmission line fault location still needs effective algorism. Quiet a lot researchers devote in fault location field, some of them study on algorism innovation, some of them are on the cutting edge of application, some of them focus on improve the location reliable and accurate. Although the power fault locations had improved quickly, it still has big tolerance, some issues are remaining unsolved. Such as whether the algorism has the location results the fault condition effect the error, whether the algorism have the same location results under different fault conditions, which fault condition have a stronger effect on the location tolerance, under what fault condition the algorism located well. Take this into consideration; this paper adopted the analysis of variance toAll the main work show as below:â‘ This paper thoroughly analysis and deduce fault location, traveling wave, artificial fault location, distribution parameter, and precious integrations location, we conclude advantage and disadvantage of those algorisms., the simulation fault location ANOV proved the theory analysis.â‘¡This paper use analyses of variance as test method of judging fault location algorism. Through analyses of variance on simulation fault location algorithms, we get a F index. Through the F index , With the method of variance analyses, we can tell which factors play more effect influence in the errors.â‘¢This paper used orthogonal experimental design to select factor combinations and sequence of simulation .orthogonal experimental design can reduce simulations time while keep to the really situation. The ANOV of precise integration simulation shows that precise integration fault location was not influenced by fault conditions. |
