37、ns for Speed-Governing of Hydraulic Turbines Intended to Drive Electric Generators 1.4 2. Use of IEEE Std 125 This recommended practice should be used in conjunction with IEEE Std 1207.1 IEEE Std 125 provides recommendations regarding performance characteristics and equipment specifications relating
38、 to turbine governing systems for controlling hydroelectric units. IEEE Std 1207 provides application insight for applying these systems to hydroelectric units and offers experience-based guidance on the impact upon system performance of various specification parameters of turbine governing systems.
39、 In addition to providing recommendations regarding performance characteristics, it is the intent of the IEEE Std 125 to provide aid in preparing technical specifications for turbine governing systems for controlling hydroelectric units. Incorporation of the technical specifications contained in IEE
40、E Std 125 into a user organizations specification document is left to the users discretion with respect to organization and sequence. Features and tests detailed in Clause 5, Clause 6 and Clause 8 of this document are considered either “recommended” or “optional.” The appearance of the words “should
41、” implies this feature, function or test is recommended for all installations. The appearance of the words “may” implies this feature, function or test is optional (at the specifiers discretion). Optional items are often not implemented in the majority of installations, but may be required by some p
42、urchasers depending on their operating experience and design philosophy. The following example shows typical wording for a recommended feature: “The governor-control system should provide a means for controlling the turbine-control actuators manually.” (See 5.2.9.) The following example shows typica
43、l wording for an optional feature: “A governor-control strategy may be specified in accordance with the anticipated performance requirements of the installation.” (See 5.2.1.2.) This document applies to new governors and governor conversions. IEEE Std 1147 contains a general overview of governor con
44、versions. Only those paragraphs in IEEE Std 125 that apply to the specific equipment to be purchased should be used when preparing the procurement specification. Normative references The following referenced documents are indispensable for the application of this document (i.e., they must be underst
45、ood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies. IEEE Std 1010,
