微機(jī)綜合保護(hù)裝置是一種采用計(jì)算機(jī)技術(shù)（Microprocessor-Based Protection System, 簡(jiǎn)稱MPS）實(shí)現(xiàn)的電力系統(tǒng)繼電保護(hù)設(shè)備。它將傳統(tǒng)繼電器保護(hù)的各種功能，如電流速斷、過(guò)流保護(hù)、零序保護(hù)、負(fù)序電壓保護(hù)、差動(dòng)保護(hù)等集成在一個(gè)或多個(gè)微處理器平臺(tái)上，通過(guò)軟件編程來(lái)實(shí)現(xiàn)對(duì)電力設(shè)備的全面保護(hù)。 這種裝置具有以下特點(diǎn)： 1. 集成度高：可以大大減少硬件設(shè)備的數(shù)量和體積，簡(jiǎn)化了接線和調(diào)試工作，提高了系統(tǒng)的可靠性和穩(wěn)定性。 2. 功能性強(qiáng)：可以根據(jù)需要靈活配置和擴(kuò)展保護(hù)功能，適應(yīng)不同電力系統(tǒng)設(shè)備和運(yùn)行條件的需求。 3. 反應(yīng)迅速：由于采用了高速微處理器和算法優(yōu)化，能夠?qū)崟r(shí)快速地處理各種故障信息，提高保護(hù)動(dòng)作的準(zhǔn)確性與速度。 4. 自診斷與自恢復(fù)：具備完善的自我檢測(cè)與故障定位能力，當(dāng)出現(xiàn)異常時(shí)能及時(shí)報(bào)警并啟動(dòng)相應(yīng)的自恢復(fù)措施。 5. 人機(jī)交互友好：通常配備友好的圖形用戶界面，便于操作人員進(jìn)行設(shè)置、監(jiān)視和維護(hù)。 微機(jī)綜合保護(hù)裝置廣泛應(yīng)用于發(fā)電廠、變電站、輸配電線路等各種電力設(shè)施中，是現(xiàn)代電力系統(tǒng)自動(dòng)化、智能化的重要組成部分。
