摘要
随着我国电网的快速发展,电力体制也在不断的革新,社会各界对无功问题与电压越来越关注。这不仅仅是供电质量自身的问题,而且还对整个电力系统的经济安全运行、电气设施的使用寿命与安全隐患以及用户安全生产保障等都具有相当大的影响。在电力网络的不断拓展的同时,电网自身的结构也越发复杂,电网运行对电能管理与电压质量的要求也日益提高,不但要保证电网的安全、提高电压的合格率,与此同时还应当尽量减少电网运行维护资金、降低电网损耗。在这种情况下,无功电压调控作为整个电力系统中的重要环节,不但是保证电压质量、减少电力系统损耗的主要途径,同时也是保证电网系统安全、稳定以及经济运行的重要方法。考虑到这些,本文首先分析了电力系统无功电压调控的意义,与此同时,还提出了电力系统的无功优化、无功电压调控的详细措施,仅供参考与借鉴。
With the rapid development of power grid in China, the power system is also constantly innovating, and people from all walks of life pay more and more attention to reactive power and voltage. This is not only a problem of power supply quality itself, but also has a considerable impact on the economic and safe operation of the whole power system, the service life and hidden dangers of electrical facilities, as well as the safety and production guarantee of users. With the continuous expansion of the power network, the structure of the power grid itself is becoming more and more complex, and the requirements of power management and voltage quality for power grid operation are also increasing day by day. It is necessary not only to ensure the safety of the power grid, but also to improve the qualified rate of voltage. At the same time, we should minimize the funds for the operation and maintenance of the power grid.Reduce the power grid loss. In this case, reactive power and voltage regulation, as an important link in the whole power system, is not only the main way to ensure voltage quality and reduce the loss of power system, but also to ensure the safety of power grid system. An important method of stability and economic operation. Considering these,this paper first analyzes the significance of reactive power and voltage regulation in power system, and at the same time, puts forward the detailed measures of reactive power optimization and reactive power and voltage regulation in power system, which can only be used for reference and reference.
