摘　　要：特高压分级式可控高抗(HCSR)解决了固定高抗在限制过电压和无功补偿方面无法兼顾的矛盾,其系统调控的灵活性高,为特高压交流电网的安全、稳定运行提供了保障。HCSR各个分设备不仅具有特高压设备重量重、体积大、结构复杂等特点,分设备之间的集成设计、绝缘配合均会导致建设用地需求大幅增加,这与国家严控建设用地增量的政策存在偏差。为此,本文充分考虑户外环境因素的影响,合理利用立体化空间设计理念,创新性提出了取能电抗器区域转接母线垂直设计,以及成套装置局部GIS设计的集约化设计方案。在合理控制设备和工程建设成本的前提下,优化解决了其粗放型使用建设用地的问题。采用集约化设计后,HCSR占地可节约25%左右,效果显著。The ultra-high voltage hierarchical controllable shunt reactor(referred to as“HCSR”)solves the contradiction that the fixed shunt reactor cannot balance in limiting over-voltage and reactive power compensation.Its system has high regulation flexibility and provides guarantees for safe and stable operation of the ultra-high voltage AC power grid.Each sub equipment of HCSR has the characteristics such as heavy weight,large volume and complex structure of ultra-high voltage equipment,the integrated design and insulation coordination between each sub equipment will lead to a significant increase in construction land demand.This deviates from the policy of strictly controlling the increment of construction land in China.Therefore,with full consideration of influence of outdoor environmental factors and reasonable utilization of the concept of three-dimensional spatial design,a vertical design of the transfer busbar in the energy taking reactor area as well as an intensive design scheme for the local GIS design are creatively proposed.Under the premise of reasonable control of equipment and engineering construction costs,the problem of extensive use of construction land has been solved.After adopting intensive design,the land occupation of the HCSR can be saved around 25%of land area with significant results.
