在功控方式下，可設(shè)置目標(biāo)功率和負(fù)荷率，自動控制機(jī)組負(fù)荷。在熱應(yīng)力控制投入下，熱應(yīng)力計(jì)算程序分別給出建議升負(fù)荷率、降負(fù)荷率。

在壓控方式下，可設(shè)置目標(biāo)壓力和壓變率，自動控制機(jī)前主汽壓力。在鍋爐輔機(jī)系統(tǒng)發(fā)生故障，發(fā)出快卸信號時(shí)，可自動投入壓控方式，由汽機(jī)維持主汽壓力。

DEH收到CCS主控器發(fā)來的CCS請求信號后，可轉(zhuǎn)為CCS方式。在CCS方式下，系統(tǒng)接收CCS的給定指令控制機(jī)組負(fù)荷。

4)       一次調(diào)頻

一次調(diào)頻可根據(jù)實(shí)際轉(zhuǎn)速與給定轉(zhuǎn)速的偏差，自動調(diào)節(jié)油動機(jī)的開度，形成轉(zhuǎn)速比例調(diào)節(jié)，從而穩(wěn)定網(wǎng)頻。

l  限制保護(hù)功能

1)      超速限制

在油開關(guān)跳閘期間，當(dāng)轉(zhuǎn)速超過3090r/min時(shí)，快速關(guān)調(diào)門。當(dāng)轉(zhuǎn)速小于3060r/min時(shí)，控制系統(tǒng)恢復(fù)到轉(zhuǎn)速控制方式運(yùn)行，調(diào)門開度受轉(zhuǎn)速PID控制。

在負(fù)荷大于10%期間，發(fā)生油開關(guān)跳閘時(shí)，快速關(guān)調(diào)門，同時(shí)控制系統(tǒng)切換到轉(zhuǎn)速PID方式，轉(zhuǎn)速目標(biāo)給定3000r/min。2秒后控制恢復(fù)到轉(zhuǎn)速PID方式，將機(jī)組轉(zhuǎn)速維持到3000r/min。

在負(fù)荷大于30%期間，若遠(yuǎn)方線路開關(guān)跳閘甩負(fù)荷，當(dāng)加速度超過預(yù)定值時(shí)，快關(guān)調(diào)門。當(dāng)加速度小于零時(shí)，控制系統(tǒng)恢復(fù)控制，由一次調(diào)頻轉(zhuǎn)速反饋維持機(jī)組轉(zhuǎn)速穩(wěn)定。
