Abstract

A step by step method for determining controlled and conventional series compensation requirements is developed. The Montana 500 kV transmission system is taken as an example in this study. A base transfer rating of 2200 MW for the system already exists, and it is assumed that as its power loading increases, controlled series compensation is needed to reinforce the system. Combination of conventional and thyristor-controlled series compensators (TCSCs) is considered as a means of increasing the system transfer capability. Powerflow and transient stability studies are performed to rate and size the series compensators. The TCSC reactance control capabilities are established for steady-state and transient conditions. An installation sequence is developed relating facility requirements to system loading
