DL/T 507—2014 水輪發(fā)電機(jī)組啟動試驗規(guī)程（英文版）內(nèi)容簡介

This standard is prepared in accordance with Notzjication on the development and revision plan of the secondbatch energy industrial standards in 2011 issued by National Energy Administration [GNKJ （2011）No.252].

This standard is structured and organized in accordance with Standard GB/T 1.1-2009 Directives for standardization-Part 1： Structure and drafting of standards.

The standard is a revision to standard DL/T 507-2002 Start-up test code for hydro-generating units （hereinafter referred to as the previous standard）. Compared with the previous standard， the main technical changes include：

——Revised the limit on run-out （peak-to-peak value） for unit operation.

——Revised allowable values of horizontal and vertical vibration （peak-to-peak value） of turbine head cover with rated speed greater than 375 rpm to 750 rpm and allowable value of horizontal vibration （peak-to-peak value） of the frame at stator core， and added explanation on the characteristics of allowable values.

——Explained in details the parameter adjustment test for service water supply； and explained in details the short-circuit test for station service transformer by means ofhydro-generating units.

——Added test on injection-type ground protection of hydro-generating units.

——Revised loading and load shedding test of hydro-generating units； and added test on thermal stability of hydro-generating units.

——Clarified requirements for test on dynamic water closing service gate or inlet valve of turbine and test on closing ring gate ofhydro-generating units.

——Added requirements on simultaneous'load shedding test of multiple generating units that share a single waterway.

——Cancelled the requirement for 30-day comnussioning.

內(nèi)容簡介

《DL/T827-2002 燈泡貫流式水輪發(fā)電機(jī)組啟動試驗規(guī)程(英文版)》是根據(jù)國家經(jīng)濟(jì)貿(mào)易委員會電力司《關(guān)于確認(rèn)1999年度電力行業(yè)標(biāo)準(zhǔn)制修訂計劃項目的通知》（電力[2000]22號文）的計劃安排制定。

我國大中型燈泡貫流式水輪發(fā)電機(jī)組（以下簡稱“燈泡貫流式機(jī)組”或“機(jī)組”）發(fā)展迅速，自20世紀(jì)80年代初起步至90年代，已建成馬跡塘、百龍灘、凌津灘、大源渡、貴港、飛來峽等安裝有大型燈泡貫流式機(jī)組的水電站近40座。

但在機(jī)組啟動驗收方向一直參考DL507-1993《水輪發(fā)電機(jī)組起》動試驗規(guī)程，而沒有統(tǒng)一的標(biāo)準(zhǔn)。由于燈泡貫流式機(jī)組自身的特點，給機(jī)組的啟動試驗和交換驗收工作帶來不便。

本標(biāo)準(zhǔn)的編寫主要總結(jié)了國內(nèi)已建和在建水電站的燈泡貫流式機(jī)組啟動試運行試驗的經(jīng)驗，參考了DL/T507-2002標(biāo)準(zhǔn)，并吸收了國外引進(jìn)設(shè)備中的相關(guān)技術(shù)要求。

通過本標(biāo)準(zhǔn)的實施，以規(guī)范燈泡貫流式機(jī)組的啟動試驗程序，統(tǒng)一相應(yīng)的專業(yè)用語和俗稱，指導(dǎo)燈泡貫流式機(jī)組的啟動試驗和交接驗收工。

本標(biāo)準(zhǔn)是對DL/T507-2002標(biāo)準(zhǔn)的補充，是國家電力基本建設(shè)施工中燈泡貫流式機(jī)組成套設(shè)備啟套設(shè)備啟動試運行試驗的依據(jù)，也是機(jī)組投產(chǎn)移交考核的主要內(nèi)容。

本標(biāo)準(zhǔn)的附錄A為資料性附錄。

本標(biāo)準(zhǔn)由電力行業(yè)水電站水輪發(fā)電機(jī)標(biāo)準(zhǔn)化技術(shù)委員會提出并歸口。
