[0001] WIND POWER SYSTEM AND METHOD USING WEARTHER RESEARCH FORECASTING [0002]

The present invention relates to a wind power generation system and method using a weather prediction model, which improves power generation prediction through accurate prediction of a target area, compares the power generation predicted value with current power generation in real time, To the manager server so that the manager can appropriately take measures so as to maximize the efficiency of the electricity utilization, and to a wind power generation system and method using the weather prediction model.

Generally, wind power generation and solar power generation are new and renewable energy generation technologies that use pollution, infinite winds and solar power anywhere in the world, and have little harmful effect on the environment and can use the land efficiently.

In recent years, many countries are concerned about the development of renewable energy due to problems such as harmfulness due to existing power generation facilities and resource depletion.

In particular, because wind power is used as a power source, it can be developed only when the wind blows over a certain wind speed.

Therefore, it is necessary to predict the amount of power generated by wind power generation in order to increase the utilization of power due to wind power generation.

If wind power generation forecasts are available, electricity trading will be more smooth in the electricity market and the flexible operation of the power generation complex will be possible.

However, since the wind power generation system up to now does not have a prediction concept, there is a problem that the efficiency of electricity utilization is lowered because the amount of electricity produced by the wind power generation can not be grasped in advance.

In other words, general thermal power generation and nuclear power generation can predict the result value according to input materials, but it is difficult to predict the generation amount in advance because the wind power generation is dependent on wind speed and wind direction, There is a problem that is difficult to operate.

In other words, if the electricity production can be predicted in advance, it is possible to operate the electric system more efficiently by quickly determining where to send the generated electricity. However, if the electricity production amount can not be predicted, the over- Efficiency will be inferior.

1 is a block diagram of a wind power generation system using a weather prediction model according to an embodiment of the present invention.

As shown in FIG. 1, the wind power generation system using the weather prediction model according to the present embodiment includes a wind power generation device 100 for generating electric power using wind power and supplying electric power to a designated point in KEPCO, A predicted power generation amount predicting device for predicting the wind direction and wind speed at a point where the wind power generation device is located according to a weather prediction model and predicting the power generation amount of the wind power generation device in advance according to a predicted result And a control unit for controlling the electric power generated by the wind power generator to be supplied to a designated position and providing the electric power generation amount prediction information generated by the electric power generation amount prediction apparatus to the electric power generating unit, When the power difference is more than the reference value, A communication signal automatic output unit 1000 for automatically outputting a communication signal to the electric power generator manager under the control of the control unit 300, And an administrator server 2000 receiving information of the apparatus and information of the power generation amount predicting apparatus and receiving information through a communication signal automatic output unit when a notification signal is generated.

The wind power generator 100 is an ordinary wind power generator, and generates electricity by an external wind and provides electricity produced at a predetermined position.

The power generation prediction apparatus 200 receives an integrated Unified Model (UM) data from a weather station. This preprocessing process generates initial and boundary data.

Then, the basic meteorological factors such as wind direction, wind speed, temperature, humidity, rainfall, and air pressure from the Auto Weather System (AWS) of the Meteorological Agency and the additional weather conditions such as the underground temperature, sunshine, visibility, Radiosonde is a radio radiosonde that receives information, and measures various weather factors such as wind profiler, radiometer and temperature of 30km or more in high-rise atmosphere, humidity, air pressure, wind direction, From the meteorological data will be provided to perform the data assimilation.

Next, the weather prediction model (WRF) is performed by combining the pre-processed data and the moving data with the numerical prediction model (UM) data.

Next, the wind direction and wind speed predicted values are extracted from the results of the weather prediction model, and analyzed, stored, and transmitted. Then, the wind power generation amount is predicted using the wind direction and wind speed prediction value.

The predicted power generation data is reported to KEPCO and utilized as basic data to efficiently distribute electricity.

Hereinafter, the Jeju region will be described as an example.

In other words, the Unified Model (UM) data is provided and preprocessing is performed. Additional weather information such as wind direction, wind speed, temperature, humidity, rainfall, pressure, and ground temperature, sunshine amount, visibility distance, cloud height (cloud height) from the AWS can be obtained from the automatic weather system (Radiosonde) that measures and transmits various weather elements such as temperature, humidity, air pressure, wind direction and wind speed of 30 km or more in high-rise atmospheres from the radiosonde We will perform the data assimilation by receiving related data.

Next, the weather prediction model (WRF) is performed by combining the pre-processed data and the moving data with the numerical prediction model (UM) data. Next, the wind direction and wind speed predicted values are extracted from the results of the weather prediction model, and analyzed, stored, and transmitted. Next, the wind power generation amount is predicted using the predicted wind direction and wind speed.

Meanwhile, when the difference between the electric power production forecasting device and the actual amount of generated electric power is out of the standard range, it is notified to the manager through the manager server 2000 to guide the user to take proper measures. For example, It is preferable to notify the KEPCO administrator because there is a problem with the electric distribution.

In other words, KEPCO manages the distribution of electric power efficiently based on the information of the electric power production forecasting device. If the electric power predicted value and the current electric power production amount differ by more than 10%, KEPCO administrator should re-adjust the electric power distribution. It notifies the manager to KEPCO Manager so that they can take action at a fast pace.

To this end, the control unit of the present invention receives pre-calculated power generation amount prediction data from the power generation amount predicting device and simultaneously receives data on the amount of power currently being produced, compares the data with each other, And outputs it to the KEPCO administrator server 2000 through the KEPCO administrator so that the KEPCO administrator can take appropriate measures.

That is, when the notification condition occurs, the control unit 300 outputs the information on the notification status to the administrator server 2000 through the communication signal automatic output unit 1000 and guides the information to be resolved within a short time, The first relay switch RY1 and the second relay switch RY2 are connected in parallel to the first relay switch RY1 and the second relay switch RY2. A two-circuit connection switch sw2, and a communication control unit 1120. [

The power source unit 1110 applies power to its own power source.

The first relay switch RY1 is provided on one side of the output terminal of the power supply unit to switch the power output from the power supply unit.

The second relay switch RY2 is provided on the other side of the output terminal of the power source unit to switch the power source unit output from the power source unit.

The third relay switch RY3 is coupled to the output terminal of the second relay switch and generates a magnetic force when the second relay switch is switched.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the third relay switch.

The second communication signal output power switch sw2 is driven by the third relay switch so that power is supplied to the communication signal output control unit 1140 to induce a communication signal to be displayed through the communication signal output unit 1150 It plays a role.

The communication control unit 1120 switches the second relay switch to induce the third relay switch to be switched so that the first circuit connection switch and the second communication signal output power supply switch are switched, The third relay switch is turned off, and at the same time, the switching state of the first circuit connection switch and the second communication signal output power switch configured to be interlocked with the first relay switch is maintained, It plays a role to sustain.

The present invention is also characterized in that it comprises a circuit board 1131 for operating the circuit, a wire piece 1132 for connecting the power supply for operating the communication signal control unit, a first magnetic holding means 1133, a second magnetic holding means 1134, Means 1133a, a gap 1134a, and a manual operation switch 1135. As shown in Fig.

The circuit-operating piece 1131 contacts the first circuit connection switch sw1 to relay the power supplied from the first relay switch to continue the flow of power.

The communication signal output control unit power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131. When the circuit operation iron piece 1131 is turned on, power is supplied to the communication signal output control unit 1140 Thereby inducing the communication device to operate.

The first magnetic holding means 1133 is provided at the lower end of the circuit operation steel plate 1131 and has a lower end in the form of a bar magnet having an S pole, sw1 and the circuit-operating iron piece 1131 are always kept in the off-state.

The second magnetic holding means 1134 is provided on the upper portion of the first circuit connecting switch sw1 and has a bar magnet shape having an S pole at the upper end and a first magnet holding The circuit breaker 1133 is pushed to push the circuit breaker 1131 up to maintain the electrically turned off state and the circuit breaker 1131 is pulled up when the third relay switch is operated so that the S The N pole constituting the upper part of the body of the first magnetic holding means 1133 and the N pole constituting the lower portion of the body and the S pole constituting the lower portion of the body of the first magnetic holding means 1133, When the first relay switch is magnetically coupled to the first magnetic holding means 1133 while the first relay switch is in the close position and the first relay switch is turned on at the same time the operation of the third relay switch is stopped, State And then maintains the power supply state through the first relay switch. At this time, when the wire for circuit operation is operated by the operation of the third relay switch, the wire for connecting the power of the communication signal output control part is automatically operated so that the communication signal is outputted to the outside.

The auxiliary magnetic holding means 1133a is installed at the lower end of the circuit operation steel plate 1131 in a state of being spaced apart from the first magnetic holding means 1133 by a predetermined distance and has a lower end in the form of a bar magnet having an S pole, When the third relay switch is not operated, the circuit breaker 1131 is lifted from the first circuit connection switch sw1 to keep the circuit in a disconnected state while the third relay switch is in operation, The operating wire 1131 is lowered to maintain the ON state of the first circuit connecting switch sw1.

Particularly, the auxiliary magnetic holding means 1133a affects the second magnetic holding means 1134 even if the first magnetic holding means 1133 is blinded, so that the off state of the first circuit connecting switch during the third relay switch non- And is magnetically coupled with the second magnetic holding means during the operation of the third relay switch to maintain the ON state of the first circuit connecting switch sw1.

The gap 1134a is provided so as to surround the periphery of the N pole of the second magnetic holding means 1134 and the second magnetic holding means and the first magnetic holding means are not directly coupled to each other when they are magnetically coupled, So that the first magnetic holding means and the second magnetic holding means can be separated more naturally from each other by the action of the spacing agent at the time of disassembly. If the spacing agent is not present, the body of the first self-holding means and the body of the second self-holding means are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, further spacers are provided so that the first magnetic holding means and the second magnetic holding means can be easily separated.

The reason why the spacing agent is provided only around the N pole of the second magnetic holding means is that the first magnetic holding means and the second magnetic holding means must be separated from each other when the relay switch is not operated, Pole and the S-pole of the second magnetic holding means are opposed to each other and the separated state can be easily maintained. If the spacing agent is wrapped to the S-pole of the second magnetic holding means, the strength of the S-poles of the first magnetic holding means and the second magnetic holding means is weakened by the interference of the spacers when the third relay switch is not operated The maintenance of the separation state may become unstable.

Accordingly, in the present invention, the spacers are provided only on the N pole of the second magnetic holding means to facilitate the separation of the first magnetic holding means and the second magnetic holding means, and when magnetic coupling is performed, So that the magnetically coupled state can be easily maintained. In practice, when the first magnetic holding means and the second magnetic holding means are coupled to each other, the N pole of the first magnetic holding means and the S pole of the second magnetic holding means come close to each other and are strongly magnetically coupled Even if the relay switch is turned off, the falling state of the circuit breaker 1131 is maintained, so that the ON state of the first circuit connecting switch sw1 can be maintained.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connection to a power supply for outputting a communication signal. When the user operates the wire to interrupt the operation of the communication signal, So that the operation of the communication signal output unit is stopped so that the communication signal is no longer output.

Hereinafter, the operation of the communication signal automatic output unit 1000 will be described.

First, a control relation for outputting a communication signal will be described. In the control unit, the controller applies power to the second relay switch to operate the third relay switch. Accordingly, the first circuit connection switch sw1 and the communication signal output power switch sw2 are turned on by the operation of the third relay switch, and the power is applied to the communication signal output control unit 1140 to display the communication signal.

When the first circuit connection switch (sw1) is activated, the control unit interrupts the operation of the second relay switch to cut off the operation of the third relay switch, and simultaneously operates the first relay switch.

On the other hand, if the operator turns off the first circuit connection switch and the communication signal output power switch during the communication signal output, the control unit recognizes the first circuit connection switch and the communication signal output power switch. Then, the second relay switch is operated to operate the third relay switch, It is possible to maintain the closed circuit while simultaneously returning the power output to the communication signal control unit 1140 and to continuously operate the communication signal output unit 1150. [

That is, according to the present invention, if the notification factor is not solved, the communication signal is continuously output to induce the notification factor to be solved.

That is, when the control unit applies the switching signal to the second relay switch and the first relay switch, the power is restored and the communication signal is automatically output. Accordingly, even if the communication signal is blocked It is possible to induce the operator to reliably solve the cause of the communication signal.

If it is no longer necessary to output the communication signal, the control unit no longer applies the power supply signal to the first relay switch and the second relay switch. In this case, the user manually operates the manual switch 1135 to intercept the communication signal .
