Title: Innovations of Shaohua Jiao in Turbine Generator Technology

Introduction

Shaohua Jiao is a notable inventor based in Beijing, China. He has made significant contributions to the field of turbine generator technology, holding 2 patents that focus on improving 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 sets. This innovative 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. 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 by Jiao 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, specifically those with a capacity of 300 MW and above. The method is implemented when shaft torsional oscillations occur, ensuring that the torsional stress relay will trip some generators of the power plant according to a real-time generated trip strategy. This approach helps to inhibit shaft torsional oscillation and safeguard the units, thereby avoiding tremendous economic losses caused by tripping all generators.
