本発明は、太陽電池の出力が常に最大になるように制御
する太陽光発電装置の最大出力制御方式％式％
太陽電池はその温度により、その出力特性が第５図に示
すように変化する。素子温度が低い時の出力特性はＴ１
のようになり、素子温度が高い時はＴ、のようになる。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a maximum output control method for a solar power generation device that controls the output of a solar cell to always be at its maximum. The output characteristics change as shown in FIG. The output characteristic when the element temperature is low is T1
When the element temperature is high, it becomes T.
即ち、出力電流Ｉ＝Ｏの時の電圧（開放重圧■。）が素
子温度が低い時は高く、素子温度が高い時は低くなる。That is, the voltage when the output current I=O (open-circuit pressure ■) is high when the element temperature is low, and low when the element temperature is high.
また、太陽電池は日射量により、その出力特性は第６図
に示すように変化する。即ち日射量が犬の時の出力特性
はり、のようになるが、日射量の小さい時はり、のよう
になる。Furthermore, the output characteristics of the solar cell change depending on the amount of solar radiation, as shown in FIG. 6. In other words, when the amount of solar radiation is a dog, the output characteristics are as shown below, but when the amount of solar radiation is small, the output characteristics are as shown below.
なお、第５図及び第６図において、縦軸は出力電流を示
し、横軸は出力電圧を示す。また、Ｐｍａｘは最大出力
点を示す。Note that in FIGS. 5 and 6, the vertical axis shows the output current, and the horizontal axis shows the output voltage. Further, Pmax indicates the maximum output point.

が変化し、最大出力を利用できず効率が悪いという問題
がある・そこで・太陽電池を常に最大電力点で使用する
ようにする最大電力点追尾制御装置が開発されている。As mentioned above, the output characteristics of the solar cell 21 change depending on the element temperature and the amount of solar radiation, so if the solar cell is used at a fixed voltage, the output characteristics will change due to changes in the amount of solar radiation and temperature, making it impossible to utilize the maximum output. Therefore, a maximum power point tracking control device has been developed that always uses the solar cell at its maximum power point.
従来、太陽光発電装置において、太陽電池の出力が常に
最大出力になるように制御する所謂最大電力点追尾制御
装置としては、常に出力電圧を微小変化させ、変化前の
出力電力と変化後の出力電力を比較し、後者が低い場合
は反対方向に電圧を変化許せ、常に最大出力点を求める
方法がある。Conventionally, in solar power generation equipment, the so-called maximum power point tracking control device that controls the output of the solar cell so that it always reaches the maximum output constantly changes the output voltage slightly, and calculates the output power before the change and the output after the change. There is a method of comparing the power, and if the latter is lower, allowing the voltage to change in the opposite direction, always finding the maximum output point.
また、他の最大電力点追尾制御装置としては、例えば特
開昭５８−６９４６９号公報に開示されたものがある。Further, as another maximum power point tracking control device, there is one disclosed, for example, in Japanese Patent Laid-Open No. 58-69469.

る。FIG. 3 is a block diagram showing the configuration of the maximum power point tracking control device. In the figure, 21 is a solar cell, 22 is a main inverter, 23 is a load, 24 is an auxiliary inverter, 25
is the control circuit. The control circuit 25 detects the output voltage V and the output current I of the solar cell 21 and determines the output power at that time since the output power P-output current characteristic of the solar cell 21 is shown in FIG. In addition to calculating P = V The output point of the main inverter 22 is controlled in such a way that the output point of the solar cell approaches the maximum power output point Pmax.
上記のように、太陽電池の出力特性を無視し固定電圧で
運転する方法は最初から効率が悪いことを承知で使用し
ているから設置した太陽電池を活用しきれないという所
謂設備利用率が悪いという欠点がある。As mentioned above, the method of ignoring the output characteristics of solar cells and operating at a fixed voltage is used knowing that it is inefficient from the beginning, so the installed solar cells are not fully utilized, which is the so-called poor equipment utilization rate. There is a drawback.
また、出力電圧を微小変化移せ、最大出力点を見つけ出

力点を判定できず制御遅れとなり同様にハンチングを起
こすという問題点がある。Further, the method of detecting the maximum output point by making small changes in the output voltage has the problem that the control device becomes expensive and that hunting occurs due to an increase in control delay. Also,
By calculating the output power P=VXI when the load current of the solar cell 21 is slightly changed by the control circuit 25 shown in FIG. 3 and comparing the power P before the change and the power P after the change, the maximum power point is determined. The method of tracking Pmax also has the problem that the maximum power point cannot be determined instantaneously, resulting in control delay and hunting.
本発明は上述の点に鑑みてなされたもので、簡単な構成

The output control method of the solar power generation device was configured to control the DC/AC converter so that the output of the solar cell reached the maximum output.
