This standard specifies the usage conditions, system performance, component performance, test items and setting principles, technical documents, as well as packaging, transportation, and storage of the AC excitation system and self parallel excitation static excitation system for large steam turbine generators. This standard is applicable to the excitation system of AC exciter and self parallel excitation static excitation system of 200MW and above steam turbine generators. The excitation system of steam turbine generators below 200MW can be implemented as a reference. For self compound excitation systems, except that the performance of the compound excitation unit should be specified by both the supply and demand parties, other requirements can refer to these technical conditions. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
