摘要

针对国内尚无海底电缆无功规划类原则的现状

对海缆线路感性无功补偿问题进行了研究。文章采用集中参数模型和负荷形状系数对海底电缆及末端负荷进行建模

并依据《国家电网公司电力系统无功补偿配置技术原则》中的有关规定

对海缆无功补偿地点、补偿容量、分组方案和补偿效果进行了经济技术分析

建立以成本和网损费用最小化为目标函数的无功规划数学模型

形成1套较为完整的海底电缆无功规划方案

用于指导工程实际。最后以110 kV嵊泗联网工程为案例对上述规划方案进行验证

证实其效果良好。

Abstract

In view of the status that no guideline on reactive power planning of submarine cable is available in China

a study on inductive reactive power compensation of submarine cable is made.The concentrated parameter model and load shape coefficient are adopted to establish modeling of submarine cable and end load.The economic and technical analysis is conducted in location

capacity

grouping scheme and compensation effect on reactive power compensation of submarine cable in accordance with related regulations in "Technical Principle of Reactive Power Compensation for Power System of State Grid of China"

mathematical models of reactive power planning on the objective function of minimizing costs of investment and network loss is established and a complete reactive power planning scheme of submarine cable is formed for instructing the actual project.Finally

the above plan is validated by taking 110 kV Shengsi interconnection project as actual case

and its effect is proved much perfect.
