Series Compensation Systems

GE's experience in series compensation systems dates back to 1928, when GE pioneered this technology with the first installation on the emerging US transmission grid. Since then GE has installed more than 100 systems globally, representing more than 30 GVAr of compensation.

Applications
The application of series compensation has continued to increase worldwide as transmission grid operators recognize the many benefits of these systems. Realizing maximum power transfer at the lowest possible cost is one of the greatest challenges today for transmission system operators. In meeting this challenge, series compensation systems represent a very cost effective and reliable means of increasing bulk power transfer and relieving power transmission bottlenecks.

Features and Benefits
Series compensation may also be applied to increase the dynamic stability of the transmission grid, reducing voltage variation, or to balance load between parallel transmission paths, thereby relieving transmission bottlenecks. These systems can be installed for a fraction of the cost of building new transmission lines. Series compensation has been economically justified when applied to transmission lines as short as 100 miles or less, and systems typically have a payback period of less than two years. The environmental impact is minimal-series compensation systems have typically been installed within existing substations.
