が数百ＫＷ以上の大型のものがほとんどである。Cogeneration power generation equipment uses a prime mover such as a gasoline engine to drive a generator to obtain electricity, and uses this electricity to supply hot water, space heating, etc.; Most of them are larger than KW.

電装置の需要は近年ますます増大してきている。しかし

ストも高く、小規模なシステムにまで普及するものは現
在存在していない。Demand for this cogeneration power generation device has been increasing in recent years from the viewpoint of effective energy use, energy saving, etc. However, due to its large scale, the system configuration is quite complex and the cost is high, and there are currently no systems that can be widely used in small-scale systems.

電の防止など高度な制御システムを構成する必要がある
からである。In other words, even if configured on a small scale, in order to perform interconnected operation with the electric power (distribution) system in terms of phase and voltage, it is necessary to connect, disconnect, control the amount of power generated and overcurrent during interconnected operation, and reverse power transmission. This is because it is necessary to configure an advanced control system to prevent such problems.
さらに、機関の始動、熱回収についても同様に高度の制
御が要求される。Furthermore, a high degree of control is similarly required for engine starting and heat recovery.

のため小規模システム普及の隘路となっていた。This means that in small-scale systems, the equipment and control systems are expensive relative to the power generation capacity, which has been a bottleneck for the spread of small-scale systems.

The objective is to provide a combined heat and power generation device that can generate electricity.

駆動することを要旨とするものである。[Means for Solving the Problems] In order to achieve the above object, the present invention houses an induction generator connected to an AC power distribution line and an internal combustion engine directly connected to the induction generator in an integrated heat insulating case. A hot water tank is installed above the tank, and a heat exchanger that uses the exhaust gas from the internal combustion engine as a heat source is installed inside the hot water tank.The bottom of the hot water tank is also used as a cold water intake port, which flows out from below the hot water tank and connects the internal combustion engine along the way. A circulation waterway is connected to the engine cooler and opens as an outlet at a higher location than the cold water intake in the hot water tank, while the induction generator is only a generator driven by an internal combustion engine. The main idea is that it can also be driven as a starting motor for an internal combustion engine.

電量が円滑に変化できる。(Function) According to the present invention, since the induction generator is excited by the interconnected AC distribution line, it is possible to avoid problems such as overcurrent due to voltage and phase differences when interconnection is turned on. The induction generator is not only a generator driven by an internal combustion engine, but also a starter motor for the internal combustion engine.
By simply connecting to the grid at around the synchronous speed and then applying torque in the opposite direction to bring it above the synchronous speed, power generation can be achieved without causing any problems during grid connection, and without any electrical or mechanical switching. Furthermore, the degree of slip from the synchronous speed changes depending on the amount of torque applied, and the amount of power generation can smoothly change.
また、内燃機関からの排気は温水タンク内の熱交換器の
熱源となり、排熱利用が行える。Furthermore, the exhaust gas from the internal combustion engine becomes a heat source for the heat exchanger in the hot water tank, allowing waste heat to be utilized.

で冷やされ、該冷却器の熱交換で温められら水は再度温
水タンクに戻るので、内燃機関の排気以外の排熱も利用
でき、効率のよい省エネルギー化ができる。Furthermore, the internal combustion engine is cooled by a cooler that uses water from the hot water tank as a refrigerant, and the water is warmed by heat exchange in the cooler and returns to the hot water tank again, so waste heat other than the exhaust from the internal combustion engine can also be used. Efficient energy saving is possible.
そして、前記冷却器がある循環水路は上方に設置した温
水タンクの底部付近を冷水取入口とし、この冷水取入口
よりも高所に排出口を開口するので、自然対流を利用で
き、循環用のポンプは不要である。The circulation waterway where the cooler is located has a cold water intake near the bottom of the hot water tank installed above, and an outlet opening higher than the cold water intake, so natural convection can be used and the circulation No pump required.
一方、内燃機関は誘導発電機を含めて一体の断熱ケース

It is configured to be operated (operated) by a controlled operation command signal.
次に、使用法及び動作について説明する。Next, usage and operation will be explained.
誘導発電機８はガスエンジン７の始動電動機を兼ね、そ
の始動のための電力は既設の配電線ｌから得る。The induction generator 8 also serves as a starting motor for the gas engine 7, and the power for starting it is obtained from the existing power distribution line 1.
その結果、誘導発電機８が始動後発電状態に移行しても
何等の切換、投入、同期調相などの手段を必要としない
でガスエンジン７のトルク制御＝スロットルの制御のみ
で極めて円滑に始動電力の供給を受けた配電線に電力を
送出できる。As a result, even when the induction generator 8 transitions to the power generation state after starting, it does not require any means such as switching, turning on, or synchronizing phase adjustment, and can be started extremely smoothly just by controlling the torque of the gas engine 7 = throttle control. Power can be sent to the distribution line that receives the power supply.
この間のトルクと回転数の状況は、第２図に示す通りで
あり、誘導発電機８が始動電動機として回転を始めたの

ンジン７の出力トルクに応じた同期速度よりわずかに速

水温等の条件および最適にコントロールされたトルクす
なわちスロットル１６の開度により運転を継続する。The situation of torque and rotational speed during this time is as shown in Figure 2. After the induction generator 8 started rotating as a starting motor, the gas engine 7 started and the rotational speed rose, exceeding the synchronous speed. Instantly, the induction motor 8 changes into a generator, rotating at a slightly higher rotation speed than the synchronous speed corresponding to the output torque of the gas engine 7, and is optimally controlled according to conditions such as power consumption and water temperature of the hot water tank 12. The operation continues depending on the torque, that is, the opening degree of the throttle 16.
この最適にコントロールする条件としては、当然使用電
力量が少なく温水の需要も少ないなどの条件、例えば夜
間などにおいては装置を停止することも含まれる。この
制御のパターンの一例を第３図に示す。Conditions for optimal control include, of course, conditions such as low power consumption and low demand for hot water, and for example, stopping the device at night. An example of this control pattern is shown in FIG.

て始動トルクの低減をはかり回転数が始動に充分な値に
達した後、圧縮逃し機構を解除する手段を設けることに
よって、始動を容易にすることが可能である。However, in a normal reciprocating internal combustion engine such as the gas engine 7, a very large torque may be required in the compression stroke at the time of starting, and the induction generator 8 cannot be driven by the torque generated at the time of starting as an induction motor. It also occurs in the case of In this case, if the induction motor is single-phase, try to increase the starting torque by using a repulsion start type or capacitor start type, or by installing a compression relief mechanism in the cylinder section of the internal combustion engine to reduce the starting torque and increase the rotation speed. Starting can be facilitated by providing means for releasing the compression relief mechanism after a sufficient value has been reached.

で調整する。On both sides of the connection point between the induction generator 8 and the distribution line 1.9 and on the line connected to the induction generator 8, power sensors 4a, 4b and 4c are installed as power amount and power flow direction detectors.
The amount of mixture of fuel and air supplied to the gas engine 7 is adjusted by changing the slot valve 16 so that the amount of power generated by the induction generator 8 is adjusted according to the power consumption based on the output. .

。In particular, when the power consumption is low such as at night, the operation may be stopped, or when the power consumption is low but the heat exchanger 29 consumes a large amount, the switch 1 is connected to the load side of the distribution line 9.
The ratio of power and heat can be controlled in accordance with the power and heat load by energizing the heater 13 in the hot water tank 12 through 0 and further through the power regulator 11 as necessary.

Furthermore, the hot water tank 12 can obtain heat from a heat exchanger 29 that uses exhaust gas from the gas engine 7 as a heat source. The jacket 8d acts as a heat exchanger, and heat can also be obtained from the water jacket 8d.

By obtaining power from the existing distribution lines, even if the state shifts to a late-start type state, power can be smoothly transmitted to the distribution lines that have been supplied with starting power without requiring any means such as switching, turning on, or synchronizing phase adjustment. It is possible.
