1 概述
RCS-985R/S/TJ微機(jī)機(jī)組保護(hù)裝置是根據(jù)國家電力公司科學(xué)技術(shù)項目合同SPKJ010-02,于
1999年1月開始研制。
RCS-985R/S/TJ采用了高性能數(shù)字信號處理器DSP芯片為基礎(chǔ)的硬件系統(tǒng),雙CPU結(jié)構(gòu)并
行處理。是真正的數(shù)字式機(jī)組保護(hù)裝置。
RCS-985R/S/TJ適用于容量在200MW及以下的汽輪發(fā)電機(jī)、水輪發(fā)電機(jī)、燃?xì)廨啺l(fā)電機(jī)
等發(fā)電機(jī)機(jī)組,并能滿足電廠自動化系統(tǒng)的要求。
RCS-985R/S 發(fā)電機(jī)保護(hù)根據(jù)相似保護(hù)功能分開,相對獨立的原則,將主保護(hù)、后備保護(hù)、
異常運行保護(hù)合理分配到兩個裝置中,共同提供一臺發(fā)電機(jī)所需要的全部電量保護(hù)。
RCS-985TJ電廠變壓器保護(hù),采用主后一體化的方案,完成一臺兩圈變壓器所需要的全部電
量保護(hù),適用于電廠的主變、啟備變、高廠變保護(hù)。按照反措要求,對于電廠的出線電壓等級為
220kV的變壓器,按照完全雙重化配置。
