する。Detailed Description of the Invention (Field of Industrial Application) This invention refers to a generator mounted on the output shaft of a ship (which operates as a generator or an electric motor depending on selection). This invention relates to a method for controlling the output of a motor (referred to as a motor), particularly when operating as an electric motor.
（従来技術）
近年、船舶においても他の分野と同様省エネルギー化が
促進されている。(Prior Art) In recent years, energy conservation has been promoted in ships as well as in other fields.
例えば、省エネルギー化の一環として、船舶の主機から

テムがある。For example, as part of energy conservation efforts, economizers (
This heat energy is used to generate steam and rotate a turbo generator to generate electricity.This electricity covers the electricity required on board (the electricity consumed on board), and further increases the amount of electricity generated above. If the power exceeds the onboard power requirement, the surplus power is used to rotate the shaft generator attached to the propeller shaft (this operating state is called electric motor operation), reducing the load on the main engine and improving fuel efficiency of the main engine. There is a propulsion auxiliary power system configured as follows.

いる。In this system, if the power required on board increases, if the amount of steam generated decreases due to dirt in the economizer, if the amount of power generated decreases due to a decrease in the rotational speed of the main engine due to deceleration, or if the outside temperature If the amount of power generated from the exhaust gas is less than the required power on board due to a decrease in the amount of power generated by the (referred to as time), the power supply is configured to replenish the power shortage.
ところで、上記システムにおいて、船内所要電力と排気

軸発電動機を電動機として用いるか、あるいは発電機と
して用いるかの切換に関する制御方法は、本出願人によ
り既に提供されている（特公昭５６−３０２３８号）。By the way, in the above system, a control method for comparing the power required in the ship and the power obtained from the thermal energy of the exhaust gas and switching between using the shaft generator as an electric motor or as a generator has been proposed by the present applicant. (Japanese Patent Publication No. 56-30238).
しかし、排気ガス中の熱エネルギーから得られる電力が
船内所要電力を上回っている場合に、どの程度の電力を
軸発電動機に供給するかの判断（電動機運転時の出力制

長年の経験による勘等によって、上記軸発電動機への電

た。However, when the electric power obtained from the thermal energy in the exhaust gas exceeds the required electric power on board, the decision as to how much electric power to supply to the shaft generator (output control during electric motor operation) is solely up to the operator. This was done by predicting the power that could be recovered from the exhaust gas energy at that time and the power required on board, and the adjustments were made manually. That is, the output of the shaft generator during operation of the electric motor has been controlled by appropriately operating a volume that adjusts the supply of power to the shaft generator, based solely on the operator's intuition based on many years of experience.
（発明が解決しようとする問題点）
このため、例えば、排気ガスの熱エネルギーから回収で

供給弁が全開となり、供給蒸気を急速に消費していくた
め、供給蒸気圧力が低下し、電動機運転ができなくなる
。(Problem to be Solved by the Invention) For this reason, for example, if the total power supplied to the electric motor operating time axis generator and the required power on board exceeds the power that can be recovered from the thermal energy of the exhaust gas, This forces the turbo generator to carry out a load greater than the output it can produce based on the supply steam pressure at that time, and as a result, the steam supply valve becomes fully open and the supply steam is rapidly consumed, causing the supply steam pressure to drop. , the electric motor will no longer be able to operate.
また、逆の場合には、余剰エネルギーが上記ターボジェ

ててしまうこととなり、省エネルギー化の思想に反する
ことになる。In the opposite case, surplus energy is accumulated in the form of an increase in the steam pressure supplied to the turbo generator, and when this pressure exceeds a predetermined pressure, the surplus steam dump valve opens and releases the steam to the outside. Either discharged or led to a condenser for condensation. In such a case, a portion of the thermal energy in the exhaust gas that can be used as propulsion auxiliary power is wasted to the outside, which goes against the idea of energy conservation.

る。On the other hand, it is also important for operators to constantly pay attention to changes in the onboard power requirements, changes in the rotational speed of the main engine, changes in outside temperature, etc., and determine how much power should be supplied to the shaft generator when the electric motor is operating. You will be forced to do the troublesome work of making judgments and frequently adjusting the volume.

This leads to frequent adjustment of the opening degree of the steam supply valve of the turbo generator, which cannot be said to be efficient operation.

でターボジェネレータを運転できる。(Function) As described above, the output control method of the shaft generator according to the present invention is such that the turbo generator always obtains the maximum power that can be generated from the steam pressure generated by the thermal energy in the exhaust gas at that time. If you control the steam supply valve to
The current onboard power requirement is subtracted from the maximum power that can be generated, and the remaining power is supplied to the shaft generator, so the thermal energy in the exhaust gas can always and automatically be used most efficiently as propulsion auxiliary power. . Moreover, since the output of the shaft generator, which is the load, is adjusted in response to fluctuations in steam pressure, the opening degree of the turbo generator's steam supply valve is kept almost constant, resulting in the most efficient system with no throttling loss. You can run a turbo generator in a good place.
