Description

Complex Generator

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hybrid power generator, and more particularly, to a hybrid power generator capable of simultaneously generating rotational energy and electric energy by multi-layering a plurality of rotating bodies.

In general, a generator is a device that converts mechanical energy into electrical energy. Generating electromagnetic force by electromagnetic induction action by rotational motion or linear motion, and it is based on a principle common to both large and small machines, direct current and alternator, and the like.

The magnitude of the electromotive force is proportional to the strength of the magnetic field, the length of the conductor, and the relative speed of the magnetic field and the conductor, and the direction of the electromotive force can be determined by Fleming's right-hand rule. The generator consists of a strong magnet for generating a magnetic field and a conductor that generates an electromotive force, which must be able to operate either. Generators used in practice include a rotary type and a rotary type. The rotary type is a generator in which the conductor stops and the magnetic field rotates, and the rotary type is opposite. There is an example in which a permanent magnet is used for a very small generator, but an electromagnet is generally used in which a field coil is wound around an iron core and a direct current flows through the coil. In this case, since the magnitude of the magnet can be increased or decreased by increasing or decreasing the current, the magnitude of the electromotive force can be freely changed. Even if the rotating speed is increased by using a strong magnet, the electromotive force generated in one conductor is limited to several tens of volts. Therefore, when a large number of conductors are placed in the generator and the electromotive force generated in each conductor is added in series, V can be obtained.

The generator includes an alternator for obtaining AC power and a DC generator for obtaining DC power. The alternator has many rotary type, and in this case, several slots are made in the iron core on the fixed side, and the conductor is inserted in the slot. When the stimulus rotates, each time the stimuli N and S pass, the change in the positive and negative alternating currents is completed once. That is, when the stimulus rotates at a rate of once per second, the frequency of the electromotive force obtained in the conductor is 1 Hz. However, the number of poles of the rotor is 4 pole, 6 pole, ... , The change in electromotive force at each revolution is 2 times, 3 times, ... Complete. In general, the frequency of the alternating current obtained when the rotor having the pole number p is rotated n times per second is f = pn / 2. Since the frequency of power alternating current in Korea is 60 Hz, when using a bipolar generator, the rotor must be turned at a speed of 60 revolutions per second. There is a numerical value required from the prime mover side for the rotation speed of the generator. Steam turbine can be used effectively for high-speed steam, and low-speed steam turbine is good for aberration. Turbine generators usually operate at high speeds (3,000 or 3,600 revolutions per minute) with a pole number of two, and at low speeds of less than 200 revolutions per minute for low turbines. An ordinary alternator is capable of obtaining three-phase alternating current. In this case, the entire conductor of the stator is divided by three, and the stator is shifted by 1/3 of the stator inner circumference length for two poles.

The three-phase alternating current generator rotates the field coil so that the direct current flows to the slip ring attached to the shaft, and the DC power is connected to the brush installed on the ring. A DC generator is connected to a DC power source. Also, there is a method of accommodating both the field winding and the three-phase power source for the rectifier and the rectifier on the rotor side. This is called an alternator without a brush, that is, a brushless AC generator. Since there is no slip ring or brush, the brush is not worn or replaced, so it is easy to repair. In this case, to regulate the current of the field coil, adjust the current of the small field coil on the three-phase generator side. The three-phase alternator has a large capacity and is a power source for a large power system. Capacity is three times the product of the voltage that can occur in each winding of three phases and the current that can be flowed, expressed in units of volt amperes (VA). The maximum capacity is several hundred thousand kVA for turbine generators and ten thousand kVA for turbine generators. As such, the larger the generator, the larger the dimensions and the weight, so it can not be made by technology that belongs to the highest level of electrical and mechanical. Most of the dc generators are of rotating type. This is because, when the rotor is rotated in a certain direction, the electromotive force generated in the conductor accommodated in the rotor is interchanged, and therefore, it is necessary to perform an operation of converting it into a direct current. The number of poles of a DC generator can be multipolar such as 4 or 6 poles in addition to 2 poles. The electromotive force generated in each coil of the rotating portion of the direct current generator is outputted as a direct current through the commutator and the brush. In the method of sending direct current to the field coil on the stationary side, there is a self-excitation type using a DC power source such as a DC power source such as a battery or other DC generator and a DC voltage generated by itself. Self-excitation is widely used because it has the convenience of not having to prepare power source. In the self-excitation mode, an acceleration / deceleration resistor called field resistance is used. The exciting current is added or subtracted by this resistor to change the voltage of the generator terminal. A special type of DC generator is a single-pole generator. This generator has a conductor cylinder in the rotating part and a magnetic field generated by the magnetic pole on the fixed side is directed toward the center of the shaft. It is not necessary to rectify the DC voltage appearing at the front and rear ends of the conductor cylinder. I can not get it. However, there is a large capacity of more than 100,000 A in current.

In addition, an electric motor (electric motor) is a device that converts electrical energy into mechanical energy by using the force that a current carrying conductor receives in a magnetic field. Generally, it refers to a motor. DC motors and AC motors are classified according to the type of power source. AC motors are divided into three-phase alternating current and single-phase alternating current. Generally, three-phase AC motors are used. An electric motor is a device that converts electrical energy into mechanical work using the force that a current receives in a magnetic field. Most motors produce rotational motions, but they also produce linear motions. A generator is a device opposite to an electric motor and produces electricity using mechanical energy. The motor and the generator can replace each other and replace it. Both DC and AC motors operate on the same principle. When an electric current flows into a magnetic field, an electromagnetic force (Lorentz force) occurs in a direction perpendicular to the direction of the magnetic field. A magnetic field is created by placing a magnet inside a motor, and when an electric current is supplied to the electric wire connected to the shaft, an electromagnetic force is generated and the motor is rotated by Fleming's left-hand rule. The electromagnetic force acting on the conductor is proportional to the strength of the magnetic field, the intensity of the current, and the length of the conductor.

The induction motor rotates the disk by rotating the magnet on the rotatable disk. The single-phase induction motor generates power by the rotation of the conductor cylinder as the external magnet is rotated. The three-phase induction motor rotates the rotor by applying a three-phase power source around the metallic cylindrical rotor to produce a rotating magnetic field. Lt; / RTI > The three-phase synchronous motor rotates the rotor by positioning the rotor which is the magnetic pole inside the stator with the three-phase winding. DC motors are divided into brush-type motors using brushes and brushless motors using electronic switching technology, depending on how the internal armature rotates every 180 degrees. The brush-attached motor is divided into two types according to the excitation type, decentralized type, decentralized type, lottery type and direct type. DC motors have the advantage of easy control of speed, torque and direction of rotation. However, there is a drawback in that a rectifier is required, speeding up is limited due to problems of rectification problems and mechanical strength, and a brush-equipped motor needs regular maintenance and inspection. Small DC motors usually operate at low voltages around 12V. DC motors are widely used when the speed control is easy and the speed adjustment is required such as a train, an elevator, and a rolling mill. AC motors are classified into 3-phase alternating current and single-phase alternating current, and there are induction motor and synchronous motor in each. The induction motor can be directly connected to the power source, it is simple in structure and robust, but it is inexpensive and easy to handle, making it the most used in the world. The synchronous motor rotates at a constant speed and is easy to adjust the power factor, so it is used in motors for conveyor belts, small clocks and timing motors. Three-phase alternating current generators have a large-scale reactor from about 1 KW to several thousands KW, and rarely more than 10,000 KW, and single-phase alternating current generators are used for small machines of several hundred W or less. Most of the motors can also be used as generators.

In addition, a motor generator is a power supply unit in which a motor and a generator are directly connected or a belt or a gear is interposed between them. Electric generators are used to denature, convert or flow power. In most cases, the motor is an induction motor, and the generator is a dc generator, which is a combination of a synchronous motor and a synchronous generator, a synchronous motor and a dc generator. In the motor generator, the motor and the generator are installed on the same pedestal, and both are directly connected. In addition, there are many cases where a dedicated operation panel is installed, and a main switch, an ammeter of the electric motor, a breaker and a fuse to open when an overcurrent, a voltmeter on the side of the generator, an ammeter, and a voltage regulator are mounted. In order to reduce the current at the start of the motor, a changeover switch may be provided to apply a voltage to the motor only when starting.

In this way, the generator and the motor have been conventionally used by combining a generator and an electric motor that perform respective functions. However, there has been a problem that a separate generator and an electric motor must be provided, and a dedicated operation panel or an additional device must be mounted.
