Title: Innovations of Jian Duo Li
Introduction
Jian Duo Li is a notable inventor based in Shanghai, China. He has made significant contributions to the field of electrical engineering, particularly in voltage compensation technologies. With a total of 2 patents, his work has garnered attention for its innovative approaches to power supply systems.
Latest Patents
One of Jian Duo Li's latest patents is a dynamic voltage compensator used in a three-phase power supply system. This device is designed to compensate for voltage fluctuations by utilizing two dynamic voltage restorers (DVR). The system allows for the selection of two phases from the three-phase power supply, with each selected phase connected in series to one of the DVRs. This innovative approach ensures that the phase voltages of the three phases can be restored to normal levels using only two sets of single-phase DVRs.
Another significant patent is a device for detecting voltage disturbances. This invention provides a method for detecting voltage disturbances by storing digitized point values of a voltage reference waveform. The method includes detecting actual voltage values and converting them into point values that correspond to the reference waveform. By comparing these point values, the system can determine if a voltage disturbance occurs, thereby improving the response speed of detection and shortening the response time.
