Research on Speed Regulation Principle and Characteristics Analysis of a Mechanical-hydraulic Governor for Diesel Engines
摘要
Abstract
Most domestic diesel generator sets in China use mechanical-hydraulic governors for throttle control.Analyzing the operating principles and characteristics of this mature and reliable governor provides critical reference for domestic independent design initiatives.This study constructs component models such as centrifugal flyweight of the governor in AMESim,and develops a diesel generator set dynamical model in Simulink based on the engine load,throttle opening and speed characteristics.Through AMESim/Simulink co-simulation,the study investigates the dynamic behavior of hydraulic buffer compensation in closed-loop speed regulation and its impact on performance.The results indicate that adding hydraulic buffer compensation effectively reduces both the settling time and speed oscillations of diesel generator sets under diesel generators load variations.This design concept not only applies to mechanical-hydraulic governors but also provides critical insights for the autonomous development of digital electronic governors.关键词
