随着我国国民经济的发展,电网中电力负荷不断增大,尤其是现代电力电子设备如整流器、电弧炉等非线性负荷大量接入电网,使电网供电质量受到严重影响,给电网输入大量的谐波,同时产生大量的无功功率,降低了系统的功率因数,而且也造成供电母线的电压波动、闪变。鉴于上面的现实,需要采取相应的措施来解决这些问题。而采用高压静止无功补偿装置(Static Var Compensator,SVC)对解决上述电能质量问题有良好的效果。正是在此课题背景下,文章设计了采用晶闸管控制电抗器(Thyristor Controlled Reactor,TCR)型高压静止无功补偿装置的研发与实现。
With the development of national economy in our country, the power load in the power grid is increasing. Especially, non-linear loads such as modern power electronic equipment such as rectifiers and electric arc furnaces are heavily connected to the power grid, seriously affecting the power supply quality of the power grid, Wave, while generating a large amount of reactive power, reducing the system’s power factor, but also caused the supply voltage fluctuations, flicker. In view of the above reality, corresponding measures need to be taken to solve these problems. The Static Var Compensator (SVC) has a good effect on solving the above power quality problems. It is against this background that the article devised the design and implementation of Thyristor Controlled Reactor (TCR) high voltage static var compensator.
