“…Thus, we need to make reasonable evaluation on breaking capacity of existing UHV CB equipment and put forward new effective suppression method, based on the accurate grasp of the UHV high SC line CB transient recovery voltage (TRV) characteristics. Presently according to practical engineering application requirements [9–11], it has been studied for TRV of EHV transmission line with 40 to 50% SC. However, it has not yet been involved in UHV high SC technology.…”

“…The presence of series compensation affects the X 0 /X 1 ratios of the system, with the reactance of the series capacitor appearing in all three sequence networks. Therefore, temporary and transient overvoltages as a result of faults, as well as circuitbreaker recovery voltages and surge arrester operation, are different than those that would appear in the uncompensated system [40], [41], [42], [43], [44], [45].…”

Basic factors and general considerations in selecting the class and means of neutral grounding for a particular ac transmission or subtransmission system are covered. An apparatus to be used to achieve the desired grounding is suggested, and methods for specifying the grounding devices are given. Transformer tertiary systems, equipment-neutral grounding, and the effects of series compensation on grounding are discussed.

This paper discusses the feasibility of using multiple series capacitors for compensating long high voltage AC power transmission lines. It starts by reviewing the available results for single capacitor compensation regarding its feasibility as well as the closed form expression for the optimal size and location of the compensating capacitor. It follows a derivation of the objective function used for assessing the effectiveness of series compensation when applying more than one capacitor. A computer routine is then used to identify the most economical locations and sizes of the capacitors that yield a maximum for the saving function. It takes into account both the increase in the line transmission capability achieved by compensation as well as the cost of the series capacitors. The results of several parameter studies will then be presented in order to demonstrate the mutual interaction between the different cost components. The effect of the line technical and economical data will then be easily recognized.The computational procedure is checked through its application to reduced special cases dealing with a single compensating capacitor for which exact analytical solutions are already available. 483 Downloaded by [University of Sussex Library] at 19:33 04 February 2015 484 Y. A. SAFAR AND M. M. SAIEDThe results pertinent to the improvement in the objective saving function achieved by applying multiple capacitors for compensation, as compared to compensation by one single capacitor, are then presented and discussed. A part of the paper is devoted to the important issue of the reactive power conditions at the terminals of the optimally compensated line.This reactive power injection can be a limiting factor in applying line series compensation.
