水轮机控制系统规范指南

[中文适用范围]： 本国际标准包含描述水轮机调速系统及其性能所需的有关技术数据。其目的是统一并因此便于在招标规范和技术投标中选择相关参数。它还将作为制定技术保证的基础。本标准的范围仅限于水轮机调速级别。此外，为了便于理解，还就电厂控制回路以及一次和二次频率控制（另见附录 B）作了一些说明，但不声称是完整的。指南涵盖的重要主题包括：针对反击式和冲击式水轮机（包括双调节机组）的速度、功率、水位、开度和流量（泄量）控制；提供操作能量的手段；用于紧急停机等的安全装置。为了便于制定规范，本指南还包括数据表，这些表格应由客户和供应商在项目及合同的不同阶段填写。验收试验、特定试验程序和保证不在本指南的范围内；这些主题由 IEC 60308 涵盖。 [外文原描述]： IEC 61362:2012 includes relevant technical data necessary to describe hydraulic turbine governing systems and to define their performance. It is aimed at unifying and thus facilitating the selection of relevant parameters in bidding specifications and technical bids. It will also serve as a basis for setting up technical guarantees. The scope of this standard is restricted to the turbine governing level. Additionally some remarks about the control loops of the plant level and about primary and secondary frequency control (see also Annex B) are made for better understanding without making a claim to be complete. Important topics covered are: - speed, power, water level, opening and flow (discharge) control for reaction and impulse-type turbines including double regulated machines; - means of providing actuating energy; - safety devices for emergency shutdown. To facilitate the setting up of specifications, this guide also includes data sheets, which are to be filled out by the customer and the supplier in the various stages of the project and the contract. Acceptance tests, specific test procedures and guarantees are outside the scope of the guide; those topics are covered by IEC 60308. This second edition cancels and replaces the first edition published in 1998. It is a technical revision. It takes into account the experience with the guide during the last decade as well as the progress in the state of the art of the underlying technologies. Keywords: Hydraulic turbine, Hydraulic turbine governing systems.
