摘　　要：目前,静止无功发生器(SVG)已广泛应用于风力发电、太阳能发电等新能源发电领域。根据某公司自主研制的±10 Mvar/10 kV链式SVG,其拓扑结构为H桥级联,每相由12个链节(H桥)串联而成。详细介绍了H桥级联SVG链节的研究与功能验证。通过链节的对冲试验及其结果,验证了链节的功能和对冲试验控制策略的效果,使得链节的设计符合《链式静止同步补偿器》技术标准的要求(1.1倍过载时,能够连续运行),从而确保±10 Mvar/10 kV SVG能在工程现场正常、稳定地运行。At present,the static var generator（SVG） has been widely used in wind power, solar power and other clean energy.Based on my company developed ±10 Mvar/10 kV SVG,which is cascaded H-bridge of topology structure, each phase consists of 12 links in series.Here introduces the SVG link（H-bridge） hedge experiment in the e-quivalent of running under the rated conditions experiment content, process and experiment results.Through hedge ex-periment and experiment results of each link, the function and control strategy of each link get verified, making the design of link conform to the requirements of the technical standards （running continuously of 1.1 times overload） of ＂Cascaded Static Synchronous Compensator＂ ,to ensure ±10 Mvar/10 kV SVG can normally operate at the site of the project.
