Latest Patents

One of his latest patents is a Load Management and Control Apparatus. This invention comprises a control unit that measures system voltage and power flow states to make arithmetic decisions. By utilizing the resultant variations in voltage and reactive power, it estimates system reactance. This estimated reactance is then used to carry out control operations, establishing a unique relationship between the tap changing operation of transformers and the connection or disconnection of reactive power supply units. This innovation helps prevent frequent tap changing operations and adjusts system voltage to reduce voltage deviation while providing integrated management of reactive power.

Another notable patent is the Thyristor Converter System with Higher Harmonics Suppression. This invention features a semiconductor bridge thyristor converter circuit designed to convert AC power into DC power while suppressing higher harmonics generated by the circuit. It includes a control circuit and instrument transformers that measure voltages and currents at both the source and load sides. The control circuit adjusts the control delay angle and overlap angle of the thyristors to minimize higher harmonics as seen from the power system side.
