Abstract

To Prevent the damage of power system facilities by snow accretion on transmission lines, a prototype expert system has been developed. The system has the basic functions of forecasting snow accretion on transmission lines and making a list of all feasible and effective deicing countermeasures to assist power system operators. As estimating of snow accretion on power lines and making countermeasure plans are very difficult to solve analytically, knowledge engineering can be an effective method for this problem. The heuristics about the effect of weather conditions on the snow accretion process on power lines and power system operation for the deicing constitutes main nile base. Simulation results based on past snow accretion accident data show that the proposed system is very premising.

전선착설로 인한 전력설비에의 피해를 방지하기 위하여, 전선착설을 예측하고 적절한 전선착설 방지대책을 제시하는 것은, 전선착설로 인한 피해 발생의 가능성과 전력계통의 안정적 운영의 양 측면을 동시에 고려하여야 하기 때문에 고도한 판단과 결단이 필요한 문제로써, 지식공학적 수법을 적용하는 것이 매우 효과적인 분야이다. 이에 따라, 전선착설의 예측과 방지대책 수립에 관련된 경험적 지식을 지식베이스화하여 전문가 시스템을 구축하고, 사례 데이터를 이용한 시뮬레이션을 통하여 제안 기법의 유효성을 확인하였다.
