ABSTRACT
This chapter discusses the different planning aspects that deal with the choice of shunt reactors and their application in power systems. it lists the other types of reactors, such as current-limiting reactors, filter reactors, neutral grounding reactors, capacitor reactors, smoothing reactors, duplex reactors, motor-starting reactors, load-balancing reactors, and their applications. The chapter also discusses the design and constructional details of the different types of extra-high-voltage (EHV) shunt reactors. It describes the four-reactor scheme with a neutral reactor to extinguish the secondary arc current by neutralizing the interphase capacitance. An underexcited synchronous machine behaves similar to a reactor absorbing lagging vars from the system. Passive reactive var compensation is provided by shunt capacitors and shunt reactors. The application of shunt reactors to compensate for a portion of the charging current has been recognized by EHV system designers as a practical and economical method of controlling voltage rises.
