Technical regulations for automatic high-frequency cut-off generator set in power system1 ScopeThis document specifies the basic requirements, configuration principles, and setting calculations for the configuration and configuration of automatic high-frequency cut-off generator sets in the power system. And the principle of coordinated configuration with unit high frequency protection and steam turbine overspeed protection. This document is suitable for high-frequency control of large power grids and high-frequency control of isolated power grids that are disconnected from the main grid after an accident. Outgoing local power grid and Enterprise power grids with self-supplied power plants can be implemented by reference.2 Normative referencesThe content of the following documents constitutes an indispensable clause of this document through normative references in the text. Among them, dated quotations Only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to This document. GB 38755 Safety and Stability Guidelines for Power Systems GB/T 38969 Technical Guidelines for Power System DL/T 1234 Technical Specification for Power System Security and Stability Calculation3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Over-speed protection control of turbine; OPC When the speed of the turbo-generator set exceeds the set value or reaches the specified limit A control that automatically opens the regulating valve after the rotation speed to maintain the unit running at the rated rotation speed. [Source. DL/T 1309-2013, 3.6, with modification] 3.2 Generator overfrequency protection When the frequency value of the generator set is higher than the set value, it will send out a warning signal or corresponding protection action according to the setting.4 General requirements4.1 The automatic high-frequency cut-off of the power system (hereinafter referred to as the high-frequency cut-off) measure belongs to the third line of defense for the stable operation of the power system. This is an emergency control measure taken to prevent the system frequency from rising sharply after a serious failure of the power grid. 4.2 When the power system has excessive active power, the transient frequency of the system exceeds the normal control range, and may cause system stability problems At the same time, the configuration of high-frequency cutting device should be considered. 4.3 The power system high-frequency cut-off configuration should include different types of generator set combinations, grid structure and operation mode, etc. 4.4 The power system high-frequency cutting plan should be formulated, organized and implemented by the power grid operation department, and checked regularly. When the system condition has When major changes are made, it should be reconfigured. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 40592-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 40592-2021_English as soon as possible, and keep you informed of the progress.
