本标准涉及火力发电厂中汽轮机调速器控制和汽轮发电机超速保护。特别排除在考虑范围之外的是单阀和受控抽汽式汽轮机、机械驱动汽轮机、自动启动/停机系统、汽轮机监控仪表、蒸汽旁路系统和汽轮机进水预防（TWIP）系统。本标准旨在制定化石燃料发电厂用汽轮机控制系统功能设计规范的最低要求。

This standard addresses steam turbine governor controls and overspeed protection of steam turbine generators in fossil power plants. Specifically excluded from consideration are single valve and controlled extraction turbines, mechanical drive turbines, automated startup/shutdown systems, turbine supervisory instrumentation, steam bypass systems, and turbine water induction prevention (TWIP) systems.The purpose of this standard is to establish the minimum requirements for functional design specifications of steam turbine control systems for use in fossil fueled power generation plants.
