2 保護(hù)功能配置及典型配屏方案
對(duì)于一個(gè)發(fā)電機(jī)，配置兩個(gè)獨(dú)立的保護(hù)裝置 985R 和 985S，每個(gè)裝置均有獨(dú)立的出口跳閘

口跳閘回路也完全獨(dú)立于電量保護(hù)。對(duì)于變壓器保護(hù)，根據(jù)現(xiàn)場(chǎng)要求配置。
2.1 保護(hù)功能對(duì)照表
AIGCRCS-985R/S/TJ系列發(fā)電機(jī)組保護(hù)裝置是一種專(zhuān)門(mén)針對(duì)電力系統(tǒng)中的發(fā)電機(jī)設(shè)計(jì)的微機(jī)型繼電保護(hù)和安全自動(dòng)控制裝置。該系列產(chǎn)品主要包括RCS-985R（型號(hào)中“R”可能代表“Regular”，常規(guī)或增強(qiáng)型）, RCS-985S（“S”可能代表“Supervisor”，監(jiān)督或高級(jí)），以及RCS-985TJ（“TJ”可能是特定型號(hào)或者技術(shù)改進(jìn)版本）等不同型號(hào)。
這些保護(hù)裝置具備全面的發(fā)電機(jī)保護(hù)功能，如定子繞組溫度、過(guò)電流、低電壓、勵(lì)磁回路故障、匝間短路、失步、振蕩閉鎖等，并能實(shí)現(xiàn)發(fā)電機(jī)的各種運(yùn)行狀態(tài)監(jiān)視與控制，包括啟停機(jī)控制、同期并列控制、調(diào)速器接口等功能。此外，它們通常配備有自診斷和遠(yuǎn)方通信接口，便于實(shí)時(shí)數(shù)據(jù)采集、遠(yuǎn)程監(jiān)控以及與調(diào)度中心的自動(dòng)化系統(tǒng)無(wú)縫對(duì)接，提高了發(fā)電機(jī)組的安全穩(wěn)定性和運(yùn)行效率?？傮w而言，RCS-985R/S/TJ系列發(fā)電機(jī)組保護(hù)裝置是電力系統(tǒng)中不可或缺的重要設(shè)備之一。
