の血要負荷に商用電源が停電した場合に給電することを
目的として非常用発電装置が設置されている。(bl Description of the Prior Art) In recent years, Birzongs and various other plants have been using emergency power generation to supply power to essential loads such as fire hydrant pumps, splinter bombs, emergency lighting, and safety equipment in the event of a power outage. Equipment is installed.
一方、省エネルギー化が進むにつれて全体の熱エネルギ
ー消費量の低減、即ち、認合効率の向上が問題となって
きた。On the other hand, as energy saving progresses, reducing the overall thermal energy consumption, that is, improving recognition efficiency, has become a problem.
これらを解消する手段の一つとして非常用発電装＠を兼
用しまた前述の運転方式の採用が急増している。As one of the means to solve these problems, the use of an emergency power generation system @ and the above-mentioned operation method are rapidly being adopted.

低品位燃料ケ利用することが多い。It is common for many of these power generation devices to be operated only during the day and shut down at night and on holidays.In addition, in order to reduce exhaust gas pollution, gas is used. Often used as fuel.
内燃機関にこれらの燥料を月」いた場合の欠点と【７て
始動時における所要時間が長＜ｔｒることである。The disadvantage of using these drying agents in an internal combustion engine is that it takes a long time to start the engine.

容易であるが、休止中における商用電源の停電において
は急速始動が不可能となる。As mentioned earlier, since we have the heavy responsibility of ensuring that the emergency load is illuminated, in the event of a power outage on the commercial side that is running in parallel with the commercial power supply, we need equipment to detect this and to make adjustments in advance. If the load is prepared in advance, it is easy to supply power to the emergency load, but in the event of a power outage of the commercial power supply during a standstill, rapid startup will not be possible.
