Title: Innovations of Yuansheng Li in Turbine Generator Technology

Introduction

Yuansheng Li is a prominent inventor based in Beijing, China, known for his contributions to turbine generator technology. With a total of 2 patents, he has developed innovative methods that enhance the efficiency and safety of turbine generator sets.

Latest Patents

One of his latest patents is a "Method for measuring shafting mechanical fatigue of turbine generator set." This method involves determining a lumped mass model of a turbine generator set and its parameters. It calculates a model frequency and a mode shape of the turbine generator set, acquires an angular velocity change at a machine end, and calculates a torque at a calculating section of shafting based on the model frequency, mode shape curve, and equivalent rigidity of the lumped mass model. This process ultimately leads to obtaining a torque-time history curve at the calculating section of the shafting and calculating a fatigue damage accumulative value for a dangerous section of a set shafting under certain malfunctions or disturbances.

Another significant patent is the "Method of coordinated operation for turbine-generator shafts torsional vibration protection." This invention relates to the coordinated control method of torsional stress relay in large thermal power plants' generators (300 MW and above). It is adopted when shaft torsional oscillations occur and includes a method for realizing selective trip of the generators. The method ensures that the torsional stress relay will trip some generators of the power plant according to a real-time generated trip strategy, thereby inhibiting shaft torsional oscillation and safeguarding the units.
