This standard establishes basic requirements for the control schemes of electrically controlled ac high-voltage circuit breakers rated above 1000 V. This standard is applicable to any type of power-operated mechanism and for both ac and dc control power. Only the basic control elements of the circuit breaker, including reclosing where required, are included in this standard. This standard does not include devices or circuits for protective relaying, special interlocking, and so forth, since… read more these are external to and dependent upon the specific application of a particular circuit breaker. read less

Part I of the guide discusses the effects of various aspects of the ac/dc interactions on the design and performance of dc schemes where the ac system appears as a high impedance at the ac/dc interface bus; i.e., low and very low short-circuit (short-circuit ratio [SCR]) conditions. AC systems having zero or inadequate mechanical rotational inertia, such as island schemes with no or with limited local generation, are also considered. Environmental, siting, and construction issues are not addressed. General issues, such as steady-state reactive compensation and ac and dc filter requirements, are not in the scope of this guide, but would be included in a complete study for a particular dc scheme design. In order to assist those not familiar with dc transmission and convertors, a brief description of basic rectifier and inverter operation is given in Annex A of Part I. Part II of this guide, which is bound together with Part I, considers how the ac/dc interaction phenomena described in Part I should be taken into account in the planning and the preliminary design of ac/dc systems having low or very low SCR values.
