Abstract: 本发明涉及一种含无功电流注入的光伏低电压穿越方法。现有的光伏低电压穿越方法有很多,然而并未充分利用光伏逆变器对功率的控制作用。本发明在电压跌落不严重情况下,保持光伏有功功率输出不变,尽量提供无功功率;在电压跌落较严重情况下,光伏不输出有功功率,全部输出无功功率。同时在电网不对称故障下,引入负序控制消除由负序分量引起的有功功率波动,并推导出最大无功功率设定值计算公式。本发明能根据电压跌落情况充分利用光伏对有功功率和无功功率的控制能力,在一定情况下保证有功功率输出又能最大限度的提供无功功率,有助于并网点电压的恢复。

Abstract: PURPOSE: A transparent greenhouse including a snow removal function and a wind breaking function is provided to maintain the structure of the greenhouse in the heavy snow and strong wind. CONSTITUTION: A transparent greenhouse including a snow removal function and a wind breaking function comprises the following: a greenhouse main body(10) formed with frames and a cover member(13); a heat supplying unit supplying heat to the cover member for maintaining the predetermined temperature on the surface of the cover member; a load sensor detecting the load applied to the greenhouse main body; an opening/closing valve(V) selectively supplying the heat to the heat supplying unit; a solar heat collecting unit(30) heating fluid using sunlight, and supplying the fluid into the heat supplying unit; a wind power generation unit(40) generating power for heating the fluid using wind; and a heat storage tank unit(50) supplying the heated fluid to a distributor(D). The cover member includes a convex unit(13a) for preventing snow from covering the greenhouse.

Abstract: PURPOSE: A temperature controlling hybrid greenhouse system is provided to control the temperature of a cultivation facility by selectively blowing cold/warm air into an air curtain. CONSTITUTION: A greenhouse structure (100) forms a warm cultivation space. An air curtain (200) controls the temperature inside the cultivation space by heat-exchanging air flowing into the greenhouse structure and air inside the greenhouse structure. A solar panel (300) collects solar energy. Capacitors (410,420) charge electric energy. A cold/warm air blower (500) blows air into the air curtain using the electric energy from the capacitors. The air curtain includes an air passage (210) by dividing the central area into plural rows. A blowing duct (220) connected to the cold/warm air blower is combined to one side of the air passage. A corner duct (230) connecting the air passage to corners is installed.
