摘要
Abstract
To improve the voltage quality, optimize reactive distribution and decrease losses in the region electric network, a voltage/reactive power linkage and coordinated control system for city and county electric power is developed. The system dynamically sends gateway reactive directives to country voltage and reactive control system when city reactive capacity is not enough, which depends on residuary reactive in the country electric network to compensate the reactive vacancy of city electric network in time. Considering city's 220 kV substations actual gateway reactive value and combining the province gateway reactive directives sent to city, this paper decides the gateway reactive value sending to country voltage and reactive control system, and illuminates the scheme to realize voltage and reactive linkage and coordinated control for regional electric network. Practical operation shows that the system is conducive to improving the voltage level, promote the rational distribution of reactive power, and decrease the loss of regional power grid, bringing economic and social benefits for power supply enterprises.关键词
