no. 1 Embodiment approach

[0035] 1. Structure

[0036] (1-1) Natural energy power generation plants

[0037] figure 1 It is a schematic diagram showing the overall structure of the natural energy power generation plant according to the first embodiment of the present invention.

[0038] The natural energy power generation plant shown in this figure includes a wind power generation device 10 as a natural energy power generation device, and a gas turbine power generation facility as a thermal power generation device. The gas turbine power generation facility includes a gas turbine power generation device 100 as a thermal power generation device, a control device 200 , and a user interface. This natural energy power generation plant may be constructed newly, for example, when the wind power generation device 10 is an existing facility, it may be constructed by adding a gas turbine power generation facility thereto.

no. 2 Embodiment approach

[0120] Figure 15 is a schematic diagram showing the overall structure of a natural energy power generation plant according to a second embodiment of the present invention, and is the same as figure 1 corresponding figure. In this figure, the same parts as those of the first embodiment are assigned the same reference numerals as those in the above-mentioned drawings, and description thereof will be omitted.

[0121] This embodiment differs from the first embodiment in that a solar power generator 1000 is used instead of the wind power generator 10 as the natural energy power generator. The solar power generation device 1000 is a power generation device composed of a plurality of solar panels 1100 . In addition, in the control device 200 , instead of the wind power generation prediction unit 400 , a solar power generation prediction unit 401 is provided.

[0126] Figure 17 is a schematic diagram showing the overall structure of a natural energy power generation plant according to a third embodiment of the present invention, and is the same as figure 1 corresponding figure. In this figure, the same parts as those of the first embodiment are assigned the same reference numerals as those in the above-mentioned drawings, and description thereof will be omitted.

[0127] This embodiment differs from the first embodiment in that a gas turbine power generation device 110 is added to provide a plurality of gas turbine power generation devices (two in this embodiment). The gas turbine power generation device 11 may be the same as or different from the gas turbine power generation device 10 . Like the gas turbine power generation device 100 , the gas turbine power generation device 110 exchanges the measured value 160 and the command value 170 with the control device 200 . Other structures are the same as those of the first embodiment...

Abstract

The present invention includes: a gas turbine power generation device (100) that converts reaction heat energy of fuel into electric power; a wind power generation prediction unit (400) that calculates the predicted power generation output of the wind power generation device (10) at a set time in the future; and a target calculation. The unit (511) calculates the target power generation output of the gas turbine power generation device (100) at the set time based on the predicted power generation output; the instruction calculation unit (512) calculates the power generation output of the gas turbine power generation device (100) to become the target power generation output. a command value (150) to the gas turbine power generation device (100); and the command output unit (515) outputs the command value (150) to the gas turbine power generation device (100) ahead of the response delay time of the gas turbine power generation device (100) from the set time (100). This can effectively suppress fluctuations in the total power generation output of the natural energy power generation device and the thermal power generation device.

Description

technical field [0001] The present invention relates to thermal power generation equipment integrated in a natural energy power generation device, a natural energy power generation plant incorporating thermal power generation equipment in a natural energy power generation device, and a control method thereof. Background technique [0002] In recent years, power generators using natural energy (natural energy power generators), such as wind power generators and solar power generators, have been popularized from the viewpoint of carbon dioxide reduction. However, natural phenomena including weather cannot be controlled, so the power generation output of natural energy power generation devices is generally unstable, and if such a power source is connected, the amount of power supplied to the system may become unstable. On the other hand, there is proposed a heavy oil upgrading plant that includes a gas turbine generator and a wind generator as power sources, and controls the ga...
