This guide assists users in specifying the functional requirements for transmission static Var compensators (SVCs) using conventional thyristor technology. Many sections will be useful for compensator systems using gate turn-off thyristor technology [static synchronous compensator (STATCOM)] or other semiconductor devices, or SVCs associated with high-voltage direct current (HVDC) converter stations, or industrial and distribution applications. Although this guide may not directly serve for SVCs primarily associated with industrial drives nor with the correction of load disturbances or phase unbalance, many sections will be useful also for these applications. General terms and conditions forming the commercial part of a specification for a particular project are outside the scope of this document.
