Abstract

PROBLEM TO BE SOLVED: To succeed stable operation even by shifting from a normal generation state to an emergency generation state in gas engine generation equipment adopting a lean combustion type gas engine. SOLUTION: A generator 12 is driven by means of a lean combustion type gas engine 11. Gas fuel is supplied into a main combustion chamber of the gas engine 11 through a gas pipe 13 for a main combustion chamber. Gas fuel is also supplied into a pre-combustion chamber through a gas pipe 14 for a pre-combustion chamber. The gas pipes 13 and 14 are communicated with each other by means of a connecting gas tube 20 provided with a load applying solenoid valve 21. When a governor throttle valve 14 is not fully opened, the load applying solenoid valve 21 is closest. When the governor throttle valve 15 is fully opened, the load applying solenoid valve 21 is temporarily opened for increasing the gas fuel to be supplied to the main combustion chamber. Combustion in a rich area is performed at this time, and an allowable load applying amount is increased. Shifting from a normal generation to an emergency generation is smoothly performed.

Therefore, a lean-burn gas engine that performs pre-combustion as shown in FIG. 3 is generally employed. In the lean-burn gas engine that performs the pre-combustion, the gas in the pre-combustion chamber 2 is ignited by the spark plug 1 and the gas in the main combustion chamber 3 is ignited by the flame of the pre-combustion chamber 2. The energy of the flame by the pre-combustion chamber 2 is 10 4 to 1 of the energy of the spark plug 1.

[0008] Here, the use conditions of a gas engine power generation facility employing a gas engine driven by gas fuel alone will be described. In the past, gas engine power generation equipment employing a gas engine driven solely by gas fuel was only permitted to operate while being connected to a commercial power source at all times. Banned by legal regulations. However, since May 1994,
Regulations have been relaxed, and even a gas engine power generation facility employing a gas engine driven by gas fuel alone can use both normal power generation and emergency power generation if certain conditions are satisfied. The "certain conditions" are conditions for using an earthquake-resistant conduit (gas pipe) that can withstand vibration of 300 Ga1 or more as a gas pipe.

It is to be noted that the dual use of the normal power generation and the emergency power generation means that, when there is no system failure (normally), the power supply is connected to the commercial power supply and the received power is controlled, for example, so that the commercial power supply can be used. At the time of power failure (emergency), it means that power is continuously supplied from the gas engine power generation equipment to an important load by, for example, selectively cutting off the load side.

In a gas engine power generation system using a lean-burn gas engine, the allowable load input (load input whose instantaneous frequency fluctuation falls within 10% at the time of load input) with respect to the rated output. It is as low as 20 to 25%. This is because a lean-burn gas engine burns in a lean region (lean region) and is therefore less sensitive to load input. Therefore, the gas engine power generation equipment using the lean-burn gas engine has no problem when it is connected to a commercial power supply for normal use. Has a low allowable load input, so there is concern about driving. In addition, the lean-burn gas engine has a problem in that it is difficult to control the air-fuel ratio, and particularly when the load is low, the air becomes rich and the control is difficult. As described above, the low allowable load input amount and the difficulty of control during low load operation, combined with the gas engine power generation equipment using the lean-burn gas engine,
I am worried about driving in an emergency. In particular, hospitals,
Where the critical load that contributes to human life is used as an emergency load, regulations on the combined use of regular power generation and emergency power generation have been relaxed, but there are concerns about actual use.
