摘　　要：提出以共轭梯度法进行交互式区间逼近,求解电力系统满足安全约束条件下,考虑经济和环境保护的多目标优化问题。由该算法所提供的多个有效解中,决策者可根据系统的各种运行方式及时灵活的选择满意解,使系统的运行总保持在整体上达到最优。整个计算过程交互进行,既作了定量计算,又充分发挥了专家或运行人员的智能决策作用。经三机电力系统实例试算表明,该算法是有效的。且收敛性好,计算速度快,是一种具有较好实际应用前景的算法。The paper presents a method of conjugate gradient for interactive interval approximation in order to solve the multi-objective optimal problems which are influenced by economy and environment tinder the condition of secure constraint of power system. this algorithm provides many effect solutions. According to various patterns of system operation, decision-makers may timely and flexibly select a satisfactory solution in order that the system operation is wholely optimal. The whole procedure is interactive. That is, on one hand, the quantitative result is obtained. On the other hand, the wisdom of experts or operators is brought into full play. Practical calculations throught a three-machine system show that the algorithm is efficient. It can satisfy the requirement of good convergency and quick computing speed. The prospect of its application is hopeful.
