The present invention relates to a power generation control system and a control method of tidal power plant, and in particular, as an integrated management technology of a remote measurement control system, a decision making system, and a main monitoring control system, for realizing optimal generation by integrating real-time data and predictive data. The present invention relates to a power generation control system for tidal power plants and a control method thereof.

In general, a power generator that generates electricity using coal, oil, or nuclear power is typically a thermal power plant, a hydroelectric generator, and a nuclear power plant.

Thermal power plants use fossil fuels, which not only deplete fossil fuel resources, but also cause serious damage to the environment due to pollution, and hydroelectric power plants must submerge large areas. There is a problem that causes damage to the natural ecosystem.

In addition, the nuclear power plant has a problem in safety due to the use of nuclear fuel, and is contaminated with the environment by the waste and pollutants of nuclear power generated in the power generation process has emerged as a serious threat to life.

In order to solve such a problem, a power generator using nature includes a solar power generator, a wind power generator using wind power, and an tidal power generator using a difference between tides of the sea.

Among them, the conventional tidal power generator is a freshwater dam at high tide, discharged at low tide and rotates the generator turbine using the free fall.

However, tidal power generators require not only enormous facility costs due to the construction of a huge dam on the coast or a wide range of coasts, but also the destruction of ecosystems because many parts of the sea are cut off from the sea. In the process of passing through the turbine, fish deaths occur, and power generation is possible only at low tide, and power generation is not possible at high tide, and it is inferior in terms of power generation efficiency. There was this.

Even in this situation, in Korea, importing all of the crude oil, it is required to build a tidal power plant using natural energy in order to supply low-cost, pollution-free energy.

Considering this situation, Korean Patent Publication No. 2001-18693 (Automatic Water Level / Hydraulic Control Device and Its Method by Analysis of Power Load Characteristics), Dong-Ho 2004-66989 (Hydrogen Power Generation System Using Tide Only) ) And 2004-86969 (tidal power generation system).

In other words, in Korean Laid-Open Patent Publication No. 2001-18693, the power consumption is unilaterally biased when viewed nationwide by driving the dynamometer unintentionally when the position of the tank falls to a low level rather than considering the power consumption load pattern. To solve this problem, the water level detector detects the water level from the water tank, the power consumption detector that detects the amount of power consumed during the day, and outputs a signal, and detects the power load pattern regularly introduced from the power consumption detector, and detects it from the water level detector. After the input signal is input, the control unit for sending a DC signal to adjust the water level according to the power load pattern, the drive unit driven by the signal sent from the control unit, the AC current supplied to the drive unit to control by the DC signal sent from the control unit Including a switching unit, the power consumption detection unit By from the power consumption pattern which is input to the control unit inhibiting the drive of the drive unit in case of a high load, it presents a method that can reduce power consumption in the high-load time.

In addition, in the above-mentioned Patent Publication No. 2004-66989, in order to solve the problem of power generation by the drainage of seawater as much as the stored capacity, and the power generation amount is weak and its efficiency is low, a large capacity reservoir is formed and Construct a split wall to divide the water inlet and the water outlet, and install a generator on the wall to store the seawater in the water inlet at high tide. Doing.

In addition, the Patent Publication No. 2004-86969 discloses a water tank and a water level installed with a first sensor to detect the water level when storing or discharging in a freshwater facility by using the tidal difference between the tide and the low tide of seawater. In the small reservoir, the large reservoir and the small reservoir where the second sensor is installed, the drop formation is controlled so that the drop height is controlled by preset information within the predetermined height and the position of the power generation aberration according to the water level of the low tide and the high tide. A large number of power generating aberrations arranged on the drop forming apparatus transversely in front of the device, the large reservoir and the small reservoir, and electrically connected by the operation of the generation aberration of the drop forming apparatus, which are rotated by the drop of the high and low tide. Power generation unit, operation detection unit, water level detection of large and small reservoirs, variable control of falling-off formation device, and high and low tide of seawater As sensed by the predetermined information has proposed a tidal power generation apparatus comprises a structure including the control device control of the respective sluice.

Tidal power generation is a method of generating potential energy by converting the potential energy according to the water level difference between the sea and George into kinetic energy by using the difference between tides generated by introducing seawater into artificially created George.

Tidal power generation is similar to hydroelectric power generation, but requires twice a day to operate power generation and hydrology. Operation is aimed at maximum power generation considering the amount of tidal water flowing in from the upstream of the reservoir and the amount of tidal water coming from the sea due to George's limited water storage. There are many difficulties in optimizing power generation than hydroelectric power generation, large facilities, and high frequency of operation.

Tidal power generation is generally divided into single-flow and double-flow generation according to the number of tides. In any case, it is usually called a single-flow type because only one direction of flow is used in tidal power generation.

The operation mode of tidal power generation repeats the generation standby, generation mode, drain standby, and drain mode.

1 is a conceptual diagram of a cycle of a single flow creative tidal power generation.

In tidal power generation mode, the gate is closed and the tidal water is introduced into George through the turbine / generator. In drainage mode, the gate is opened and the turbine / generator is drained back to leave George empty.

As shown in Figure 1, when the tide is higher than the water level by a certain level determines the head head suitable for power generation to start the development and stop the power generation when the tide is lowered close to the level.

Although tidal power generators are installed a lot of water generators, a lot of water gates should be installed to increase drainage capacity, and these facilities are composed of a large-scale system that is about five times larger than hydroelectric power plants.

The tidal power of the sea is infinite, and since George's water storage is limited, it is the characteristic of tidal power plants to determine the start generation head car and the minimum power head car that can produce the maximum power by predicting the tide and the water level. Power generation becomes an important variable in production.

According to the technique disclosed in the above publication, since the generator is operated or stopped in accordance with the change of the tide which is changed in real time in the tidal power plant, it is difficult to determine the start time and the stop time of the generator, and accurately determine the time point. There was a problem that can not maximize the amount of power generation.

In addition, there was a problem in that the operation of the transmission and distribution system, the control of the flood gate, and the control timing of the auxiliary equipment in the power plant cannot be accurately predicted.

An object of the present invention is to solve the problems described above, to provide a power generation control system and a control method of tidal power plant that can increase power generation efficiency by predicting the tide and predicting the optimum start and end time of power generation. It is for.

Another object of the present invention is to provide a power generation control system and a control method of an tidal power plant that can efficiently manage generators, transmission and distribution facilities, flood gates and auxiliary equipment in power plants.

As described above, an object of the present invention is that the tidal amount is relatively constant in relation to tidal power generation, and the characteristics of tides are regionally different, but the prediction is possible because of using a regularly occurring marine phenomenon.

In order to achieve the above object, the power generation control system of a tidal power plant according to the present invention is a system for controlling power generation of a tidal power plant on the basis of real-time data, and a remote measurement control system for measuring the tide level and transmitting measured tide information, the remote A decision system that receives the tide information from a measurement control system and outputs predicted tide information for determining power generation start and end tide for optimal power generation; and receives the tide information from the remote measurement control system, and receives the tide information from the decision system. It receives the predicted tide information, determines the start and end time of power generation, executes power generation start and end commands, controls and monitors various facilities of the tidal power plant, and displays the information about the predicted tide and the measured tide. Includes main monitoring and control system for comparison and output The.

In addition, in the power generation control system of the tidal power plant according to the present invention, the decision system includes a tide database unit for storing information of a predetermined period of tide information input from the telemetry control system, and the information stored in the tide database unit. And an optimum power generation simulation unit for predicting the maximum power generation start and end tidal power generation possible by the tidal power predicted by the tidal current predicting unit.

In addition, in the power generation control system of the tidal power plant according to the present invention, the main monitoring control system is the main monitoring control unit for determining the start and end time of power generation, the generator and auxiliary equipment controlled and monitored by the main monitoring control unit, in the power plant It includes facilities, transmission and water substation facilities and hydrological facilities, and the aid and reservoir facilities monitored by the main monitoring and control unit.

In addition, the power generation control method of the tidal power plant according to the present invention to achieve the above object is to calculate the amount of generation by changing the effective drop and the amount of the effective drop divided by a predetermined interval required for power generation under the facility constraint conditions of the power plant And determining the maximum generation amount by comparing the generation amounts, and determining the tide level in the case of the maximum generation amount as the generation start and end tide level.

In addition, in the power generation control method of the tidal power plant according to the present invention, the step of measuring the sea tide in order to obtain real-time data as a facility constraint condition of the power plant, storing the real-time data to obtain the tide data for each predetermined period in the past Step, the step of predicting the tide from the past tide data stored in the storing step further.

The above and other objects and novel features of the present invention will become more apparent from the description of the specification and the accompanying drawings.

1 The amount of power generated during tidal changes sensitively depending on the timing of the head start. Accordingly, the present invention aims to determine the head difference at which the maximum amount of power generation occurs by calculating the amount of power generated by varying the amount of power generated from the lowest possible head to the rated head difference at every tidal current.

2 is a simulation conceptual diagram for calculating the optimal start time and stop time of power generation according to the present invention.

The simulation of the determination of the optimum start and stop time of the generator for the tide and george level changes is performed by calculating the amount of generation that can be generated by changing the tide by 0.1m, for example, from the lowest possible water head to the highest tide. The maximum water level is determined as the rated head difference, and the time at which the rated water head becomes the optimal power generation start point is set. Then, the stop point at which power generation ends at the time when the tide is gradually lowered to the level that becomes the lowest possible power head. Is set to.

The generator starts and stops automatically by comparing the start and stop tide of the above result to the main monitoring and control system, which will be described below, compared to the measured tide input to the main monitoring and control system.

Simulation of the tide information as described above is different depending on the size of the facility of the tidal power plant.

The input data for this simulation are 1) tidal forecast data, 2) aberration (turbine) efficiency, 3) George's capacity, and 4) situational marine information and equipment constraints.

3 is an aberration (turbine) efficiency curve provided by the manufacturer, FIG. 4 is a volumetric curve in George obtained by depth measurement, FIG. 5 is a hydrologic discharge amount curve, and FIG. 6 is a water discharge characteristic curve at drainage.

In FIG. 3, the aberration (turbine) efficiency curve shows all performance characteristics related to aberration.

In FIG. 4, the volumetric curve in George represents the level of George according to the amount of water.

In FIG. 5, the hydrologic discharge curve shows drainage capacity in George discharged to the hydrologic according to the water head difference in the Net state.

In FIG. 6, the water head difference flow rate characteristic curve indicates the drainage capacity in George at the time of drainage according to the water head difference in the gross state.

The power generated from tidal power is determined as P = 9.8HQ .

Where P is power, H is effective drop, and Q is quantity.

In FIG. 2, when power is generated from the point of time of the lowest power head possible, George's level rises from that point, and the effective drop in the above equation decreases, thereby reducing the power P and increasing the effective drop. In order to generate power from the point when the tide is the highest point after the rated head car, the quantity of power that can be generated is reduced and the power P is also reduced.

Therefore, in the present invention, the product of the effective drop and the quantity is maximized, that is, the head of the rated difference, which is the point in time at which the power P is maximized, is predicted by simulation.

In tidal power generation, power generation is shown in the above curves as follows: 1) the available head determined by the change of the George water level according to the tidal and power plant operation, 2) the efficiency curve of the aberration (turbine), 3) the volume of the George, It is determined by several factors that affect each other, such as 4) hydrologic drainage and 5) power generation.

The tidal power generation determines the maximum power generation amount according to the level of the George to determine the optimal starting and stopping time of the generator for maximizing the power generation under the limited facilities of George's capacity. It depends on the quantity.

Maximum generation amount

It has an objective function value.

Here, N is a value obtained by dividing the difference between the tide level and the George level (effective head difference) by a constant interval (constant interval is, for example, 0.1 m), and Pi is the amount of power generation in the level according to the value divided by the predetermined interval.

This prediction method predicts the tide at the point of generating maximum power while changing the value of N described above under the constraint of the power generation facility as the maximum power generation start tide.

At the end of the development, George's water level remains the highest.

In addition, the light blue line is the curve of the cross state, which represents the head head difference in tidal power generation which is the difference between the tide level and the George level, and the maroon line is the curve of the Net state, which is the maximum generation amount by the simulation according to the present invention. It is a curve which shows the effective head difference from the start point to the lowest possible tidal power generation.

That is, integrating the area of this curve corresponds to the maximum power generation amount according to the present invention.

The aberration (turbine) is automatically started by the determination of the optimum power generation start of the power plant, and the joint control of the governor and the entire facility of the tidal power plant are remotely monitored.

The data of the tide for each fixed period of time (1 hour, 6 hours, 304 hours, 24 hours) is stored, and at the same time, the average value (average value of the tide) of the data for the past periods is also calculated and stored. The tide predicting unit 202 may predict the tide changing in real time according to the past measured tide value and the currently measured tide value stored in the tide database unit 201.

For example, to stop the operation of the facility according to the value of real-time data measured by the tide measurement sensor 101 and transmitted by the data transmission unit 105 and the value predicted by the optimum power generation simulation unit 203. In this case, the main monitoring control unit 301 first stops the operation of the power transmission equipment 304, then stops the operation of the generator and the auxiliary equipment 302, and then controls the opening and closing of the hydrologic equipment.
