Description

本発明は、内燃機関の排気ガスによって駆動されるガスタービン発電装置とその始動方法に関する。   The present invention relates to a gas turbine power generator driven by exhaust gas of an internal combustion engine and a start method thereof.

従来のガスタービン発電装置は例えば特許文献１に開示されており、図５を参照して説明する。
図５に示すように、従来のガスタービン発電装置はガスタービン２は遮断弁７を介して内燃機関１の排出する排気ガスにより駆動される。遮断弁６は遮断弁７の開閉動作と逆の動作をする。同期発電機３は減速ギヤ８を設けた回転軸を介してガスタービン２に結合されて駆動されると共に、励磁装置１０より界磁電流を供給され、発生する電力を遮断器１２を介して電力系統３０へ供給する。電力系統３０には遮断器１４を介して負荷５が接続される。同期投入装置１１は同期発電機３の電圧と電力系統３０の電圧を監視し、遮断器１２を操作して同期投入を行う。抵抗器２０〜２２はそれぞれ遮断器２５〜２７を介して同期発電機３へ接続され、電力が供給される。負荷変換装置２４は入力電流を調整し、抵抗器２３により消費する電力を調整する。 A conventional gas turbine power generator is disclosed in, for example, Patent Document 1 and will be described with reference to FIG.
As shown in FIG. 5, in the conventional gas turbine power generator, the gas turbine 2 is driven by exhaust gas discharged from the internal combustion engine 1 through a shut-off valve 7. The shutoff valve 6 performs the reverse operation of the shutoff valve 7 opening / closing operation. The synchronous generator 3 is driven by being coupled to the gas turbine 2 through a rotating shaft provided with a reduction gear 8 and is supplied with a field current from the exciter 10, and the generated power is supplied via the circuit breaker 12. Supply to system 30. A load 5 is connected to the power system 30 via the circuit breaker 14. The synchronous charging device 11 monitors the voltage of the synchronous generator 3 and the voltage of the power system 30 and operates the circuit breaker 12 to perform synchronous charging. The resistors 20 to 22 are connected to the synchronous generator 3 via the circuit breakers 25 to 27, respectively, and supplied with electric power. The load converter 24 adjusts the input current and adjusts the power consumed by the resistor 23.

次に、このようなガスタービン発電装置における同期発電機３の始動方法を説明する。
遮断器２５〜２７を閉とし、抵抗器２０〜２２を同期発電機３へ接続した状態で励磁装置１０により界磁電流を供給する。その後、遮断弁７を開くと遮断弁６を介してバイパスされていた排気ガスが遮断弁７を介してガスタービン２へ供給され、ガスタービン２及び同期発電機３が回転する。これにより発電機３は発電し、抵抗器２０〜２３へ電力を供給する。抵抗器２０〜２３での電力消費によりガスタービン２の軸に負荷トルクが発生し、この負荷トルクと排気ガスのエネルギーによるガスタービン２の加速トルクがつり合う回転数でガスタービン２および同期発電機３は回転する。ここで、抵抗器２０〜２２が同期発電機３に接続されている場合につり合う回転数を同期発電機３の定格回転数よりも十分低い回転数としておく。その後、抵抗器２０〜２２を一つづつ順に遮断することにより負荷トルクが減少し、同期発電機３の回転数が上昇する。 Next, the starting method of the synchronous generator 3 in such a gas turbine power generator will be described.
A field current is supplied by the excitation device 10 with the circuit breakers 25 to 27 closed and the resistors 20 to 22 connected to the synchronous generator 3. Thereafter, when the shut-off valve 7 is opened, the exhaust gas bypassed via the shut-off valve 6 is supplied to the gas turbine 2 via the shut-off valve 7, and the gas turbine 2 and the synchronous generator 3 rotate. Thereby, the generator 3 generates electric power and supplies electric power to the resistors 20-23. A load torque is generated in the shaft of the gas turbine 2 due to power consumption by the resistors 20 to 23, and the gas turbine 2 and the synchronous generator 3 are rotated at a rotational speed at which the load torque and the acceleration torque of the gas turbine 2 due to the energy of the exhaust gas are balanced. Rotates. Here, the rotational speed balanced when the resistors 20 to 22 are connected to the synchronous generator 3 is set to a rotational speed sufficiently lower than the rated rotational speed of the synchronous generator 3. After that, the resistors 20 to 22 are sequentially cut off one by one, whereby the load torque is reduced and the rotational speed of the synchronous generator 3 is increased.

この同期発電機３の回転数が上昇する様子を図６に示す。同図のＡの範囲は例えば抵抗器２０〜２２が同期発電機３に接続されている期間である。同図のＢの範囲は例えば抵抗器２０を遮断し、抵抗器２１，２２を同期発電機３に接続している期間であり、負荷トルクが減少するため同期発電機３の回転数は上昇する。さらに抵抗器２１を遮断すると同期発電機３の回転数は定格回転数付近まで上昇する。次に、負荷変換装置２４により抵抗器２３に流れる電流を調整することで負荷トルクの微調整を行い、同期発電機３を定格回転数に調整する。その後、同期投入装置１１により遮断器１２を操作して同期発電機３を電力系統３０へ接続し、負荷５へ電力を供給する。
特開平６−１０６９９号公報 FIG. 6 shows how the rotational speed of the synchronous generator 3 increases. A range of A in the figure is a period in which, for example, the resistors 20 to 22 are connected to the synchronous generator 3. The range of B in the figure is a period in which, for example, the resistor 20 is shut off and the resistors 21 and 22 are connected to the synchronous generator 3, and the load torque decreases, so the rotational speed of the synchronous generator 3 increases. . When the resistor 21 is further cut off, the rotational speed of the synchronous generator 3 rises to around the rated rotational speed. Next, the load converter 24 adjusts the current flowing through the resistor 23 to finely adjust the load torque, and the synchronous generator 3 is adjusted to the rated rotational speed. Thereafter, the circuit breaker 12 is operated by the synchronous input device 11 to connect the synchronous generator 3 to the power system 30 and supply power to the load 5.

図５に示すガスタービン発電装置の始動方法は、抵抗器２０〜２２と遮断器２５〜２７及び負荷変換装置２４と抵抗器２３によって同期発電機３及びガスタービン２の回転数を調整して始動する方法であるので、ガスタービン２の回転数上昇を抑制するために容量の大きな抵抗器が必要となり、コスト上昇、設置スペース拡大につながると共に、それらの制御が複雑になるという課題がある。また、このガスタービン発電装置では内燃機関の排気ガスのエネルギーを同期発電機３によって電力に変換して再利用することが課題とされているが、抵抗器での電力消費を利用しているため、一部再利用しないエネルギー消費が生じるという課題があった。   The starting method of the gas turbine power generator shown in FIG. 5 is started by adjusting the rotational speeds of the synchronous generator 3 and the gas turbine 2 by the resistors 20 to 22 and the circuit breakers 25 to 27, the load converter 24 and the resistor 23. Therefore, there is a problem that a resistor having a large capacity is required to suppress an increase in the rotational speed of the gas turbine 2, leading to an increase in cost and an installation space, and a complicated control. Further, in this gas turbine power generation device, it is considered that the energy of the exhaust gas of the internal combustion engine is converted into electric power by the synchronous generator 3 and reused. However, since the power consumption in the resistor is used, There was a problem that energy consumption that was not partially reused occurred.

本発明はこのような課題を解決するためになされたもので、その課題はガスタービン発電装置の始動を少ない機器で且つ簡単な制御で行うと共に、排気ガスエネルギーの再利用を高めることが可能なガスタービン発電装置とその始動方法を提供することである。   The present invention has been made to solve such a problem, and the problem is that the gas turbine power generator can be started with a small amount of equipment and with simple control, and the reuse of exhaust gas energy can be enhanced. A gas turbine power generator and a starting method thereof are provided.

The output voltage of the generator is activated, and then the synchronous input device is operated to synchronously input the synchronous generator into the power system. Next, the induction machine is disconnected from the power system and then the first shut-off valve It is characterized in that power is supplied to the load by opening.

請求項４に記載の発明は、請求項２記載のガスタービン発電装置において、前記誘導機を電力系統と接続してから、前記励磁装置から前記同期発電機に界磁電流を供給することにより前記同期発電機の出力電圧を起動し、その後、前記同期投入装置を作動させて前記同期発電機を電力系統へ同期投入し、次に、前記誘導機を電力系統から切り離してからクラッチにより前記ガスタービンを前記減速ギヤを介して前記同期発電機と結合し、その後、前記第１の遮断弁を開とすることで負荷へ電力を供給することを特徴とする。   According to a fourth aspect of the present invention, in the gas turbine power generator according to the second aspect, the induction machine is connected to a power system, and then the field current is supplied from the exciter to the synchronous generator.

Further, since the rotational speed control of the gas turbine is not performed by the power consumption of the resistor, it is possible to increase the reuse of the exhaust gas energy.

以下、本発明を実施するための最良の形態について説明する。
図１は本発明の第１の実施形態のガスタービン発電装置の構成図である。 Hereinafter, the best mode for carrying out the present invention will be described.
FIG. 1 is a configuration diagram of a gas turbine power generator according to a first embodiment of the present invention.

同図に示すように、本実施形態のガスタービン発電装置が図５の従来のガスタービン発電装置と相違する構成は、抵抗器２０〜２３、負荷変換装置２４および遮断器２５〜２７の代りに誘導機４と遮断器１３を設けた点であり、その他の構成は同一であるので、同一構成部分には同一符号を付して重複説明は省略する。   As shown in the figure, the configuration in which the gas turbine power generator of this embodiment is different from the conventional gas turbine power generator of FIG. 5 is replaced with resistors 20 to 23, load converter 24 and circuit breakers 25 to 27. Since the induction machine 4 and the circuit breaker 13 are provided and the other configurations are the same, the same components are denoted by the same reference numerals, and redundant description is omitted.

図１に示すように、本実施形態のガスタービン発電装置は、誘導機４と同期発電機３とは同軸に両回転子が結合されており、誘導機４は遮断器１３を介して電力系統３０に接続され、電動機として作用する。   As shown in FIG. 1, in the gas turbine power generator according to the present embodiment, the induction machine 4 and the synchronous generator 3 are coaxially coupled with both rotors, and the induction machine 4 is connected to the power system via the circuit breaker 13. 30 is connected and acts as an electric motor.

次に、本実施形態のガスタービン発電装置の同期発電機の始動方法を図１及び図２を参照して説明する。   Next, the starting method of the synchronous generator of the gas turbine power generator of this embodiment is demonstrated with reference to FIG.1 and FIG.2.

まず、遮断弁６を開、遮断弁７を閉とし、ガスタービンの回転を停止状態とする。次に、遮断器１３を閉とし、誘導機４を電力系統３０の電圧で駆動する。誘導機４は電動機として作用し、同期発電機３の回転を加速する。誘導機４の作用により、同期発電機３の回転数は定格回転数に近い回転数へ上昇する（図２のＡ）。その後、励磁装置１０により同期発電機４に界磁電流を供給し、発電機の出力電圧を起動する（図２のＢ）。次に、同期投入装置１１により遮断器１２を操作して同期発電機３を電力系統３０に接続する（図２のＣ）。次に、遮断器１３を開として誘導機４を電力系統３０から切り離す（図２のＤ）。その後、遮断弁７を開として排気ガスをガスタービン２に導入することにより、排気ガスのエネルギーをガスタービン２及び同期発電機３を介して電力系統３０に供給する（図２のＥ）。なお、図２の（１）の期間の誘導機４のすべり周波数は、当該期間の発電機の周波数が同期投入装置１１の周波数判定値以内となるように選定する。   First, the shutoff valve 6 is opened, the shutoff valve 7 is closed, and the rotation of the gas turbine is stopped. Next, the circuit breaker 13 is closed, and the induction machine 4 is driven by the voltage of the power system 30. The induction machine 4 acts as an electric motor and accelerates the rotation of the synchronous generator 3. Due to the action of the induction machine 4, the rotational speed of the synchronous generator 3 increases to a rotational speed close to the rated rotational speed (A in FIG. 2). Thereafter, a field current is supplied to the synchronous generator 4 by the excitation device 10 to start the output voltage of the generator (B in FIG. 2). Next, the synchronous generator 3 is operated by the circuit breaker 12 to connect the synchronous generator 3 to the power system 30 (C in FIG. 2). Next, the circuit breaker 13 is opened and the induction machine 4 is disconnected from the power system 30 (D in FIG. 2). Thereafter, the shutoff valve 7 is opened and exhaust gas is introduced into the gas turbine 2 to supply the energy of the exhaust gas to the power system 30 via the gas turbine 2 and the synchronous generator 3 (E in FIG. 2). Note that the slip frequency of the induction machine 4 in the period (1) in FIG. 2 is selected so that the frequency of the generator in the period falls within the frequency determination value of the synchronous input device 11.

上述したように、本実施形態によると、少ない機器で且つ排気ガスエネルギーを効率よく再利用しながら同期発電機３を始動することができる。   As described above, according to the present embodiment, the synchronous generator 3 can be started with a small number of devices and efficiently reusing exhaust gas energy.

図３は本発明の第２の実施形態のガスタービン発電装置の構成図である。
同図に示すように、本実施形態のガスタービン発電装置が図１の第１の実施形態と相違する構成は、クラッチ９を設けた点であり、その他の構成は同一であるので、同一構成部分には同一符号を付して重複説明は省略する。 FIG. 3 is a configuration diagram of a gas turbine power generator according to a second embodiment of the present invention.
As shown in the figure, the gas turbine power generator of this embodiment is different from the first embodiment of FIG. 1 in that a clutch 9 is provided, and other configurations are the same. Parts are denoted by the same reference numerals, and redundant description is omitted.

本実施形態のガスタービン発電装置において設けたクラッチ９は、減速ギヤ８と共に同期発電機３の回転軸を結合する役割を有している。   The clutch 9 provided in the gas turbine power generator according to the present embodiment has a role of coupling the rotating shaft of the synchronous generator 3 together with the reduction gear 8.

次に、本実施形態のガスタービン発電装置の同期発電機３の始動方法を図３及び図４を参照して説明する。   Next, a method of starting the synchronous generator 3 of the gas turbine power generator according to this embodiment will be described with reference to FIGS.

図４において、停止状態ではクラッチ９を切り、減速ギヤ８と同期発電機３の結合を切り離す。その後の手順は、遮断器１３を開として誘導機４を電力系統３０から切り離す（図４のＤ）までは既に説明した図１の第１の実施形態に示すガスタービン発電装置の同期発電機３の始動方法と同じであるため、その説明を省略する。   In FIG. 4, in the stop state, the clutch 9 is disconnected, and the reduction gear 8 and the synchronous generator 3 are disconnected. The subsequent procedure is that until the circuit breaker 13 is opened and the induction machine 4 is disconnected from the power system 30 (D in FIG. 4), the synchronous generator 3 of the gas turbine power generator shown in the first embodiment of FIG. Since this is the same as the starting method, the description thereof is omitted.

次に、遮断器１３を開とした後、クラッチ９を入り（図４のＦ）とし、減速ギヤ８と同期発電機３の回転軸を結合させる。その後、遮断弁７を開（図４のＥ）として排気ガスの流量をガスタービンに導入することにより、排気ガスのエネルギーをガスタービン２及び同期発電機３を介して電力系統３０に供給する。なお、図４の（１）の期間の誘導機４のすべり周波数は、当該期間の発電機の周波数が同期投入装置１１による同期投入が可能な範囲となるように選定する。   Next, after the circuit breaker 13 is opened, the clutch 9 is engaged (F in FIG. 4), and the reduction gear 8 and the rotating shaft of the synchronous generator 3 are coupled. Thereafter, the shutoff valve 7 is opened (E in FIG. 4) and the flow rate of the exhaust gas is introduced into the gas turbine, whereby the energy of the exhaust gas is supplied to the power system 30 via the gas turbine 2 and the synchronous generator 3. Note that the slip frequency of the induction machine 4 during the period (1) in FIG. 4 is selected so that the frequency of the generator during the period falls within a range in which the synchronous input device 11 can perform synchronous input.

上述したように、本実施形態によると、図１の第１の実施形態に比べて誘導機４が駆動する機器が同期発電機３のみとなるため、誘導機４にはより小容量の機種を用いることが可能となり、より効率よく同期発電機３を始動することができる。   As described above, according to the present embodiment, the induction machine 4 is driven only by the synchronous generator 3 as compared with the first embodiment of FIG. The synchronous generator 3 can be started more efficiently.
