doi:10.11985/2021.02.013

Abstract

Abstract:

When the diesel generator set of the power system of the electric drilling rig is running in parallel, the periodic oscillation of power often occurs due to the interference of oil supply, accompanied by the instability of speed oscillation, voltage and frequency, which is called the problem of interactive oscillation. The purpose of this paper is to improve the control of diesel generator set to solve the problem of generator set interaction oscillation in the power system of electric drilling rig. At present, the control system of diesel generator sets mostly adopts the traditional PID control technology, which cannot effectively overcome the power oscillation caused by the fuel supply interference. Therefore, the fuzzy PID control algorithm is used instead of the conventional PID control. The mathematical model of diesel generator set is established by using Matlab/Simulink; the control effect of fuzzy PID and conventional PID on the nonlinear problems such as variable load of diesel generator set is verified respectively, and the feasibility of fuzzy PID is verified by simulation.

Key words: Matlab, diesel generator set, fuzzy PID, power interactive oscillation
