The invention discloses a DFIG (Doubly Fed Induction Generator) based direct current grid-connection generating system which comprises multiple DFIGs and a direct current power grid, wherein each DFIG is connected with a stator converter and a rotor converter; the stator converter and the rotor converter are connected with a controller; the stator converter has the functions of converting an alternating current outputted by the DFIG into the direct current while realizing the maximum wind energy tracking running of the DFIG; and the rotor converter has the functions of supplying excitation to a DFIG rotor while realizing the stable voltage control of a DFIG stator end. According to the DFIG based direct current grid-connection generating system, alternating current transmission is changed into direct current transmission for the power by directly utilizing the stator converter; the quantity of the converter is not increased; only the capacity of the stator converter is greater than the capacity of a network-side converter of a traditional DFIG wind power system; and meanwhile, the fluctuation of the voltage at the DFIG stator end does not need to be considered, so that the system structure is simple and the running property is stable; and the control for the DFIG and direct current transmission is simplified.

The present invention is a method for measuring touching position, touching energy and display device thereof. While touching position is measured, at least two sensors are installed in dispersing form under the sensing panel of touch control equipment. The sensing panel is divided into a plurality of grids. The unit energy distribution vector of the touching signal is compared with the unit energy distribution vector of the benchmark signal of each grid, therefore touching position is obtained. While touching energy is measured, at least one sensor is installed under the sensing panel. The sensing panel is divided into a plurality of grids. Touching position would be obtained by the above method for measuring touching position or other methods. The touching energy could be calculated by comparing the detected touching signal energy with energy of benchmark signal at touching position in corresponding grid. The present invention could reduce the cost, complexity and power consumption of touch control equipment dramatically.
