## Power Systems Stability HandbookThe increased use of power lines to interconnect multiple generating sources has lead to increased concern for preventing vulnerability to stability problems, in which failure of a single line can ultimately lead to the unanticipated blackout of an entire area served by a particular grid. Under deregulation, transmission lines become the weak link in the supply chain, and their vulnerability to stability problems assumes greater importance. This comprehensive reference will guide you through every aspect of improving the reliability and stability of electric transmission systems, so that the likelihood of such failures can be significantly reduced. You'll find coverage of hard-to-find information, such as the effect of high-speed breakers on stability, how to calculate unbalanced faults, multi-machine stability, and power factor control. |
