Operation and Control

摘要: A well‐designed and well‐manufactured unit can become compromised by serious operational challenges, some of which, discussed in this chapter, are outside the control plant operators. However, such a case, several ameliorating actions be taken proactive station management. Other challenges directly related to how operators run unit. All these aspects chapter. The chapter provides definition and, when required, an explanation all performance parameters. It also information on various machine curves, namely open circuit saturation curve, short capability V‐curves. Some special operating conditions include unexcited operation, negative sequence currents, overloading, loss cooling, over fluxing, out‐of‐step synchronization. Numerous industry standards have been developed, both nationally internationally, that specify required hydro generator. Such found IEEE, IEC, BS, VDE, other publications.
