Description

  Embodiments described herein relate generally to a wind power generation system.

  Conventionally, a wind power generator has been designed and operated so as to obtain the maximum power generation output corresponding to the wind power at that time, regardless of the operating state of the power system. In recent years, since this type of wind power generation equipment tends to increase, for example, when the system load is low, such as at night or on holidays, the balance between the power generation output of the power system and the load is lost, which hinders maintenance of the frequency of the power system. May come.

  In particular, small-scale power grids installed in islands and other areas have a relatively high ratio of wind power generation compared to other areas, and in order to balance power output and load, wind power generators themselves Adjustment of the power generation output may be required.

  For example, although fluctuation compensation by charging and discharging generated power with a storage battery is a technically effective measure, there is a drawback that the equipment cost is increased due to the addition of storage battery equipment. Therefore, a method is known in which an inertial response model in which control characteristics of a synchronous generator are set is provided in a control device that controls the output of wind power generation, and the power generation output is controlled based on this model.

  Also, measure the output of the synchronous generator and the grid frequency of the power system installed near the wind power generation equipment, and adjust the output of the wind power generation equipment according to the response of the synchronous generator to the frequency fluctuation of the power system Therefore, a control method for stabilizing the power system has also been proposed.

US Patent Application Publication No. 2007/0120369 International Publication No. 2010/086031

  Here, by applying the control method described above, it is possible to change the frequency of the wind power generation output for a temporary load fluctuation and realize an inertial response equivalent to that of a conventional synchronous generator, for example. is there. However, although such a control method contributes to instantaneous power generation output and load stabilization (short-term frequency fluctuation), there is still a problem about long-term frequency fluctuation stabilization.

  The problem to be solved by the present invention is to provide a wind power generation system that can continuously compensate for fluctuations in the system frequency caused by an imbalance between the load of the power system and the power generation output.

The wind power generation system of the embodiment includes a wind power generator, a thermal power generator response model, and an output adjustment unit. The wind power generator generates power using wind power as a power source. Thermal generator response model is configured to dynamic characteristic of the controlled system frequency by thermal turbine power plant to simulate, the power generation output corresponding signal corresponding to the power generation output of the thermal turbine power plant which varied according to fluctuations in the system frequency Output. The output adjustment unit adjusts the power generation output by the wind power generator based on the output power generation output equivalent signal. Here, the thermal power generator response model includes first and second dynamic characteristic models. The first dynamic characteristic model is configured to imitate a dynamic characteristic of a control system for adjusting a thermal turbine including a high pressure turbine, an intermediate pressure turbine, and a low pressure turbine to a constant rotational speed, and inputs the system frequency. Based on the input system frequency and the dynamic characteristic of the control system for speed control, an adjustment valve flow rate equivalent signal for adjusting the opening degree of the control valve for controlling the flow rate of the working fluid to be introduced into the thermal turbine. Generate and output. On the other hand, the second dynamic characteristic model imitates the respective dynamic characteristics when the high-pressure, medium-pressure and low-pressure turbines of the thermal turbine are driven by a working fluid having a flow rate corresponding to the control valve flow rate equivalent signal. The control valve flow rate equivalent signal output from the first dynamic characteristic model is input, and the input control valve flow rate equivalent signal and each of the high pressure, intermediate pressure and low pressure turbines are driven. The power generation output equivalent signal is generated and output based on the dynamic characteristics.

Hereinafter, embodiments will be described with reference to the drawings.
[First Embodiment]
As shown in FIG. 1, the wind power generation system 10 of the present embodiment includes its own wind power generation output A, a thermal power generation output B by a thermal power generator, and a renewable energy power generation output C by, for example, solar thermal power generation or geothermal power generation. The power generation system is realized.

  As shown in FIG. 1, the wind power generation system 10 mainly includes a wind power generator 3, a windmill control device 2, a frequency converter 8, and a wind power generation output control device 7. The wind power generator 3 generates power using wind power as a power source. The wind power generator 3 includes a wind turbine blade composed of a plurality of blades, a speed increaser, a generator (generator body) 9 and the like. Examples of the generator 9 include a synchronous generator such as a variable speed synchronous generator.

  The rotational force of the wind turbine blade that rotates by receiving the wind force is transmitted to the generator 9 via, for example, a rotating shaft accommodated in the nacelle or the above-described speed increaser. The generator 9 is driven by this transmitted rotational force to generate power.

  The windmill control device 2 performs pitch control and yaw control of the windmill blades. The pitch control is control for changing the angle of each blade constituting the wind turbine blade according to, for example, the wind speed. The yaw control is a control for changing the direction of the entire wind turbine blade according to the wind direction. In addition, the windmill control device 2 outputs a windmill control signal for controlling the torque of the windmill blades that rotate by receiving wind power.

  As shown in FIG. 1, the output adjustment unit 12 is a power conditioner (PCS) that adjusts the power generation output by the wind power generator 3 (the power generator 9). The output of the output adjustment unit 12 is the wind power generation output A.

  Specifically, since the voltage of the power generation output is fixed at, for example, 6.6 kV, for example, the output adjustment unit 12 adjusts the power generation output by adjusting the output current value. Further, the output adjustment unit 12 includes a frequency converter 8. The frequency converter 8 converts the electric power generated by the wind power generator 3 into a rated frequency such as 60 Hz or 50 Hz and outputs AC power.

  As shown in FIG. 1, the adder / subtracter 14 subtracts the system load D in the power system from the addition result obtained by adding the wind power generation output A, the thermal power generation output B, and the renewable energy power generation output C. The addition result of the power generation output, the system load D and the deviation) are output to the power system as the power generation output of the entire power generation system. In this case, the system frequency Fs changes according to the load / frequency characteristic E of the power system corresponding to the deviation between the total value of the respective power generation outputs and the system load D.

  Here, the wind power generation output control device 7 includes a thermal power plant governor model 5 and an adder 15 as shown in FIG. The thermal power plant governor model 5 is a thermal power generator response model configured to imitate the dynamic characteristics of system frequency control by a thermal power generator (for example, a thermal power generation output B is output). The thermal power generator is a thermal turbine generator such as a steam turbine generator. The thermal power plant governor model 5 outputs a thermal power generator output equivalent signal Pg1 as a power generation output equivalent signal corresponding to the power generation output of the thermal power generator that varies according to the fluctuation of the system frequency Fs.

  The output adjustment part 12 adjusts the electric power generation output by the wind power generator 3 (generator 9) based on the thermal generator output equivalent signal Pg1 mentioned above. In this embodiment, the output adjustment part 12 shows the example which adjusts the electric power generation output by the wind power generator 3 based on this thermal power generator output equivalent signal Pg1 and the above-mentioned windmill control signal which the windmill control apparatus 2 outputs. ing. Specifically, the adder 15 of this embodiment adds the output command (windmill control signal) from the windmill control device 2 and the thermal power generator output equivalent signal Pg1 output from the thermal power plant governor model 5. This is input to the output adjustment unit 12 as a wind power generation output command.

  As shown in FIGS. 2 and 3, the thermal power plant governor model 5 automatically adjusts the adjusting valve flow rate equivalent signal Cv according to the change in the system frequency Fs, and adjusts the thermal power generator output equivalent signal Pg1. It has a function to do. The control valve flow rate equivalent signal Cv is a signal corresponding to an opening degree adjustment signal for adjusting the opening degree of the control valve for controlling the flow rate of the working fluid introduced into the turbine, for example, in a thermal turbine generator. The thermal generator output equivalent signal Pg1 is a signal corresponding to the power generation output from, for example, a thermal turbine generator.

  As shown in FIG. 2, the thermal power plant governor model 5 is provided with a turbine governor model 5a and a thermal power turbine model 5b. The turbine governor model 5a is, for example, a dynamic characteristic model in which dynamic characteristics of a governor control system for adjusting the thermal turbine to a constant rotational speed (rated rotational frequency) are acquired in advance and simulated. It is.

  That is, as shown in FIG. 2, the turbine governor model 5 a includes a speed setter 20, a subtractor 21, a regulation rate calculator 22, a load setter 23, and an adder 24. The subtractor 21 acquires the system frequency Fs. On the other hand, the subtractor 21 acquires the rated rotational frequency on the specifications of the thermal turbine from the speed setter 20. Further, the subtractor 21 outputs a deviation obtained by subtracting the system frequency Fs from the rated rotational frequency number to the settling rate calculator 22.

  The settling rate calculator 22 multiplies the input deviation by multiplying the reciprocal of the speed settling rate. The load setter 23 outputs a signal for setting a system load corresponding to the power demand to the adder 24. The adder 24 adds the output of the regulation rate calculator 22 and the output of the load setter 23, and outputs the addition result as an increasing / decreasing valve flow rate equivalent signal Cv.

  On the other hand, in the thermal turbine model 5b, for example, in a thermal turbine generator, the dynamic characteristics when the turbine body is driven with a working fluid having a flow rate corresponding to the control valve flow rate equivalent signal Cv is acquired in advance, and this is simulated. This is a dynamic characteristic model realized in As shown in FIG. 2, the thermal turbine model 5b includes a high-pressure turbine characteristic imparting unit 25, a reheater / medium-pressure turbine characteristic imparting unit 26, a low-pressure turbine characteristic imparting unit 27, a high-pressure output ratio setting unit 28, and an intermediate-pressure output ratio. A setting unit 29, a low-pressure output ratio setting unit 30, and an adder 31 are provided.

  The high-pressure turbine characteristic imparting unit 25, the reheater / intermediate-pressure turbine characteristic imparting unit 26, and the low-pressure turbine characteristic imparting unit 27 start from the timing when the opening degree of the adjusting valve is controlled according to the adjusting valve flow rate equivalent signal Cv. Then, characteristics such as time delay until the timing at which the operation is introduced into each of the intermediate pressure turbine and the low pressure turbine and the drive control of each turbine is started accordingly are sequentially given to the control valve flow rate equivalent signal Cv.

  The high-pressure output ratio setting unit 28, the medium-pressure output ratio setting unit 29, and the low-pressure output ratio setting unit 30 are set with the ratio of the load allocated to the high-pressure turbine, medium-pressure turbine, and low-pressure turbine as the output ratio with respect to the system load. It is. For example, the high pressure output ratio setting unit 28, the medium pressure output ratio setting unit 29, and the low pressure output ratio setting unit 30 are set with output ratios of 30%, 30%, and 40%, for example, and the high pressure turbine characteristic imparting unit 25 The input from the intermediate pressure turbine characteristic imparting unit 26 and the low pressure turbine characteristic imparting unit 27 is output to the adder 31 at the output ratio thereof.

  The adder 31 adds the output components of the high-pressure turbine, medium-pressure turbine, and low-pressure turbine that are respectively input to obtain the thermal power generator output equivalent signal Pg1. As a result, the thermal power plant governor model 5 receives the system frequency Fs as shown in FIG. 2, and generates a thermal power generator output equivalent signal Pg1 corresponding to the power generation output from the thermal turbine generator as shown in FIG. Can be sought.

  Here, the horizontal axis in FIG. 3 indicates the system frequency Fs, while the vertical axis indicates the control valve flow rate equivalent signal Cv (or the thermal power generator output equivalent signal Pg1 or the like). A point R [Hz] in FIG. 3 is an adjustment valve flow rate equivalent signal Cv (opening degree of the adjustment valve) is 0 [%]. This R [Hz] is a system frequency Fs of, for example, 50 [Hz] of the rated frequency. ] Or 60 [Hz]. Further, the point F [%] in FIG. 3 is set as a dead zone that does not change the control valve flow rate equivalent signal Cv (the opening degree of the control valve) because the system frequency Fs is a frequency band close to the rated frequency. Represents that.

  Next, operation | movement of the wind power generation system 10 comprised in this way is demonstrated. As shown in FIG. 1, for example, when the system load D suddenly decreases at night or on holidays, and the power generation output of the entire system greatly exceeds the system load, the system frequency Fs increases according to the system load / frequency characteristic E. . This increased system frequency Fs is input to the wind power generation output control device 7, and is subjected to arithmetic control by the thermal power plant governor model 5, and the thermal power generator output equivalent signal Pg1 as its output is as shown in FIG. As the system frequency Fs increases, it decreases according to the settling rate.

  This decrease is transmitted to the output adjustment unit 12 through the adder 15 and decreases the wind power generation output A. On the other hand, contrary to such a situation, even if the grid load D increases rapidly, the wind power generation system 10 including the thermal power plant governor model 5 is able to compensate for the rapid increase in the grid load D. Increase A.

  Furthermore, the effect of the wind power generation system 10 of this embodiment is demonstrated based on FIG. FIG. 4 shows a response characteristic J of a conventional wind power generator that does not have the response characteristic H1, dynamic characteristic model, etc. of the wind power generation system 10 of the present embodiment when the system load suddenly decreases with respect to the power generation output of the entire system. The response characteristic K according to the technique of Patent Document 1 or 2 is illustrated.

  Here, as described above, when the system load suddenly decreases, the system frequency Fs increases. However, in the conventional wind power generator, as shown as the response characteristic J in FIG. Thus, it cannot contribute to compensation for fluctuations in the balance between the power generation output and the system load. Further, it is assumed that the technique of the above-described Patent Document 1 or 2 has a response characteristic K in FIG. 4 and instantaneously converges to zero in a long time although it has an effect of suppressing fluctuations in the system frequency. However, the system frequency fluctuation compensation effect is limited.

  On the other hand, the wind power generation system 10 of the present embodiment shows a long-term continuous fluctuation suppression response effect as shown by the response characteristic H1 in FIG. 4, and is the same as the conventional thermal power generator. In addition, it is possible to continuously contribute to stabilization of the system frequency. Therefore, according to the wind power generation system 10, it is possible to continuously compensate for fluctuations in the grid frequency caused by an imbalance between the load of the power grid and the power generation output.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. In FIG. 5, the same components as those in the first embodiment shown in FIG.

  The wind power generation system of this embodiment is replaced with the thermal power plant governor model 5 provided in the wind power generation output control device 7 of the wind power generation system 10 according to the first embodiment, as shown in FIG. A model 55 is provided. The thermal power plant governor model 55 inputs the system frequency Fs and outputs a thermal power generator output equivalent signal Pg2.

  The thermal power plant governor model 55 further includes a synchronous generator response model 55a in addition to the configuration of the thermal power plant governor model 5. The thermal power plant governor model 55 is provided with the synchronous generator response model 55a after the thermal power turbine model 5b of the thermal power plant governor model 5.

  Here, in the wind power generation system of the present embodiment, the generator 9 of the wind power generator 3 shown in FIG. 1 is configured by, for example, a variable speed synchronous generator. As shown in FIG. 5, the synchronous generator response model 55a is configured to imitate the dynamic characteristics of control performed by the synchronous generator with respect to fluctuations in the system frequency Fs, and the thermal power plant governor of the first embodiment. A thermal power generator output equivalent signal Pg2 obtained by correcting the thermal power generator output equivalent signal Pg1 (thermal power turbine output equivalent signal Pt in FIG. 5) output from the model 5 is output.

  The output adjustment unit 12 adjusts the power generation output by the wind power generator 3 (generator 9) shown in FIG. 1 based on the thermal power generator output equivalent signal Pg2 to which the above correction is applied. In this embodiment, the output adjustment part 12 has shown the example which adjusts the electric power generation output by the wind power generator 3 based on this wind power generator output equivalent signal Pg2 and the windmill control signal which the windmill control apparatus 2 outputs. . Specifically, in the present embodiment, the adder 15 adds the output command (windmill control signal) from the windmill control device 2 and the thermal power generator output equivalent signal Pg2 output from the thermal power plant governor model 55. This is input to the output adjustment unit 12 as a wind power generation output command.

  As shown in FIG. 5, the synchronous generator response model 55a includes a subtractor 59, an integrator 56, a proportional gain setting unit 57, an adder 58, an adder / subtractor 52, a turbine generator inertia force setting unit 53, and a turbine loss setting unit. 54.

  The subtractor 59 outputs the deviation obtained by subtracting the system frequency Fs from the turbine speed equivalent signal Nt described later to the integrator 56 and the proportional gain setting unit 57. The integrator 56 integrates the inputted deviation according to the dynamic characteristics of the variable speed synchronous generator, converts it to a phase angle, and outputs this to the adder 58 as a synchronizing torque component. On the other hand, the proportional gain setting unit 57 outputs a braking torque component obtained by giving a proportional gain to the input deviation to the adder 58.

  The adder 58 adds the synchronization torque component input from the integrator 56 and the braking torque component input from the proportional gain setting unit 57 to obtain a thermal power generator output equivalent signal Pg2. The adder 58 outputs the thermal power generator output equivalent signal Pg2 to the adder 15 shown in FIG. 1 and the adder / subtractor 52 shown in FIG.

  Further, as shown in FIG. 5, the thermal power plant governor model 55 automatically converts the thermal turbine output equivalent signal Pt into the thermal power generator output equivalent signal Pg2 in accordance with changes in the system frequency Fs and the thermal power generator output equivalent signal Pg2. And a function of matching the turbine speed equivalent signal Nt with the system frequency Fs. The subtractor 21 outputs a deviation obtained by subtracting the turbine speed equivalent signal Nt from the rated turbine speed signal output from the speed setter 20 to the regulation rate calculator 22.

  On the other hand, the adder / subtractor 52 inputs the thermal turbine output equivalent signal Pt output from the adder 31. Here, the turbine generator inertial force setting unit 53 sets the inertial force of the turbine body, and the turbine loss setting unit 54 sets the loss of kinetic energy of the turbine body. The adder / subtractor 52 subtracts the thermal power generator output equivalent signal Pg2 and the output of the turbine loss setting unit 54 from the inputted thermal turbine output equivalent signal Pt, and outputs the calculation result to the turbine generator inertia force setting unit 53. . The turbine generator inertia force setting unit 33 accelerates / decelerates the input calculation result to obtain a turbine speed equivalent signal Nt.

  As shown in FIG. 5, the thermal power plant governor model 55 configured as described above has the system frequency Fs as an input, and a thermal power generator output equivalent signal Pg2 corresponding to the power generation output of the thermal turbine generator corresponding to the fluctuation. Can be calculated.

  Furthermore, the effect of the wind power generation system of this embodiment is demonstrated based on FIG. FIG. 6 shows a response characteristic J of a conventional wind power generator that does not have a response characteristic H2 and a dynamic characteristic model of the wind power generation system of the present embodiment when the system load is suddenly reduced with respect to the power generation output of the entire system. The response characteristic K by the technique of patent document 1 or 2 is illustrated.

  Here, as described above, when the system load D rapidly decreases, the system frequency Fs increases. However, in the conventional wind power generator, as shown as the response characteristic J in FIG. Thus, it cannot contribute to compensation for fluctuations in the balance between the power generation output and the system load. Moreover, although the technique of the above-mentioned patent document 1 or 2 is assumed to be like the response characteristic K in FIG. 6, the effect of suppressing the fluctuation of the system frequency is obtained in the short term, but it converges to zero in the long time. However, the system frequency fluctuation compensation effect is limited.

  More specifically, in the technique of Patent Document 2, it is necessary to install synchronous generators of the same scale in parallel in addition to wind power generation equipment, which requires extra equipment costs and increases equipment costs. Further, the response of the synchronous generator varies depending on the characteristics of the governor that controls the speed / output of the prime mover, and may not necessarily be the optimum response for the system depending on the governor characteristics and the operating state of the prime mover.

  On the other hand, the wind power generation system of the present embodiment has both an instantaneous fluctuation suppression response effect and a long-time continuous fluctuation suppression response effect, as indicated by the response characteristic H2 in FIG. As with conventional thermal power generators, it can continue from the initial response and contribute to stabilization of the system frequency. Therefore, according to the wind power generation system of the present embodiment, it is possible to compensate for fluctuations in the grid frequency caused by imbalance between the load of the power grid and the power generation output in the short term and in the long term.
