Foreword

This standard is identical with IEC 61064.1991 "turbine speed control system acceptance test" (in English). This standard is equivalent translation IEC 61064.1991. For ease of use, this standard made the following editorial changes. a) Remove IEC 61063.1991 original "preface" and so on; b) to IEC 61064.1991 in the original part of the body (such as. terminology, etc.), according to China described the proper habits When compiled and unity; c) to IEC 61064.1991 Part of the original chart will be recompiled. Appendix A of this standard is a normative appendix. The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Standardization Technical Committee turbine (SAC/TC172) centralized. This standard was drafted. Shanghai Power Equipment Research Institute, Xi'an Thermal Power Research Institute Co., Ltd. The main drafters of this standard. Cheng Pei Jun, Yang Shoumin, Feng Shi Lian, Liu Chen, Ye Fen.

1 Scope and purpose

This standard applies acceptance test driven alternator speed in a given power plant turbine speed control system. Speed \u200b\u200bcontrol system System includes speed control system and overspeed protection system. For other types of turbines, all suitable may be used. Turbine speed control system and overspeed protection system acceptance test purpose is to verify the manufacturer to ensure that the indicators proposed in the book. through Often, this test is to verify these indicators and GB/T 5578 standard compliance. These indicators may include. a) speed droop; b) local speed droop; c) When an empty load, corresponding to the lower limit of the speed range synchronizer; d) slow rate of speed control system; e) stability of the speed control system; F) After the rejection to the part load and full load in the speed control system, the maximum instantaneous speed increases value; g) overspeed shutoff setting value; h) speed control system malfunction thrown under maximum instantaneous speed value to full load after. Other test procedures and selection of pilot projects not included in this standard, agreed upon by both parties.
