Latest Patents

One of his latest patents is titled "Method and system for fast reconfiguration of power supply network in tens of milliseconds after power grid failure." This invention provides a method for rapidly reconfiguring the power supply grid within milliseconds following a grid failure. The master station of this system gathers network status information from client stations located at transformer substations or power plants. It compares this data with a built-in control strategy table designed to address potential faults. Upon detecting a power grid disconnection fault, the system sends a pre-start switch-on instruction to client stations equipped with multiple breakers capable of reconnecting the grid. Once the fault is cleared, the client stations identify the fault-clearing time and send synchronous switch-on instructions to the appropriate local breakers. This mechanism allows for the disconnection and reconnection of the grid within 150 milliseconds after a disconnection event.

Another notable patent is the "State-matrix-independent dynamic process estimation method in real-time for weakly observable measurement nodes without PMU." This method relies on real-time measurement data from nodes without Phasor Measurement Units (PMUs) and data from the Supervisory Control And Data Acquisition (SCADA) system. By utilizing recursive least squares solutions, the method establishes a linear relationship between the variations of measurement parameters at nodes without PMUs and those with PMUs. This innovative approach provides high estimation precision and meets the error requirements for engineering applications.
