Low Frequency Oscillation Analysis and Oscillation Source Location Based on Oscillation Energy Part Two Method for Oscillation Source Location and Case Studies
摘要
Abstract
The total energy in a power system is consistent with the oscillation amplitude.The elements producing energy have negative contribution to the oscillation damping and are considered to be the oscillation sources.Both the generators with negative damping torque and the elements with external periodic disturbance can produce oscillation energy.The formula for the energy production of the external disturbance on a generator is derived.According to the energy flow in the power network,the sources of the oscillation energy can be found,and the energy sources are the oscillation sources.Controls at the oscillation sources can suppress the oscillation effectively.Based on the analysis of energy source and energy flow in the power network,a method using oscillation energy flow to locate oscillation source is proposed.It only uses wide area measurements and is suitable for on-line applications.The validity of the method is verified by the simulation results and the analysis results of actual oscillation accidents.关键词
