摘　　要：文中提出在输电服务定价中计入系统可靠性分量的方法,该方法包括3个项工作:①确定单位可靠性价值;②量化各类用户对输电系统可靠性的影响;③把可靠性分量整合到费率设计中。采用文中提出的方法,按照网内负荷、过网和发电等各类用户对系统可靠性的影响计算其应付费用或应得补贴。可靠性分量通过价格信号迫使系统中所有参与者(电力公司和用户)分担它们对系统可靠性的责任,并送出一个激励信息以鼓励新发电机的正确选址。该方法也反映了输电公司的长期投资回收需要。并用加拿大BCTC公司的实际例子解释了所提方法的计算步骤。This paper presents a method to develop and incorporate a reliability component in transmission pricing. The method includes the following three tasks： （1） developing a technique to establish a unit reliability value; （2） quantifying impacts of customer on system reliability; （3） incorporating the reliability component in the rate design. The proposed method calculates the charge or credit to a native, wheeling, orgeneration customer in terms of its impact on system reliability. Incorporation of the reliability component will force all players in the system （the utility and customers） to share their responsibility in system reliability through a price signal and provide an incentive message to encourage the right siting of new generations. The method also reflects the long run incremental investment requirement of a transmission company. The procedure of the proposed method has been explained using the BCTC system in Canada as an example.
