Title: Piotr Pierz: Innovator in Electric Power Line Protection
Introduction
Piotr Pierz is a notable inventor based in Wroclaw, Poland. He has made significant contributions to the field of electric power line protection, holding 2 patents that focus on innovative methods for enhancing the safety and reliability of power transmission systems.
Latest Patents
One of his latest patents is a "Method of Distance Protection of Parallel Transmission Line." This invention addresses the need for effective distance protection applicable to both series compensated and uncompensated electric power lines. The method utilizes a distance relay and involves calculating a pair of flags to indicate faulted and healthy circuits in parallel lines. Additionally, it independently calculates a flag to indicate whether a fault is internal or external. By analyzing these flags, the system can generate a trip permission signal or a block signal to protect the parallel lines from damage.
Another significant patent is the "Method of Fault Phase Selection and Fault Type Determination." This invention focuses on selecting the faulted phase and determining the fault type in electric power lines. It involves detecting fault inception and estimating fault phase current signals, pre-fault current signals, and zero-sequence current. The method aims to provide real value indicators for various types of faults, including phase-to-phase faults, three-phase faults, and ground faults.
