OPTIMAL DECISION-MAKING MODEL OF RELIABILITY DESIGN FOR PNS

The power network system (PNS) is an important part of the power System, safety and reliability is ensured only by reliability optimized design. By analyzing the influential factors of reliability allocation, the method of fuzzy synthesis evaluation based on fuzzy mathematical theory was presented to carry through optimum allocation of power network system in this paper. Namely, appointed reliability index is distributed rationally to subsystem of PNS by defining factor set of reliability level and the weight of factors, and further defining synthesis decision-making based on attachment degree of every factor. Both reliability of whole system and economic benefit are ensured by the method, and design example is given. It provides a feasible method for reliability optimum design of power system
