SUMMARY The paper presents the study on
low frequency oscillation
(LFO) mitigation in an interconnected
power system
with AC/DC parallel transmission lines (1). The
Small Signal Stability
Analysis software SSAP is developed for largescale
power system
LFO analysis. Eigenanalysis of linearized
power system
show that both interarea modes and local modes of LFO exist (0.2Hz<frequency< 2.0Hz), furthermore, weak damping (e.g.damping ratio <0.05) make the
power system
operate under the potential of oscillation. Eigenvector of each mode shows the generators are divided into groups, which may oscillate against one another. The types of division are different and each type related to one special oscillation mode.
Power System
Stabilizer (PSS)s as traditional approach to mitigate LSO were already equipped in excitation systems of all the large capacity generators and show their effectiveness. The paper studies how to apply the supplementary control of HVDC to further enhance the damping of interarea modes and suppress LFO. Doubleside AC frequency difference control for each HVDC is called the frequency difference modulation.
Power flow
and current in AC tie line and voltage at AC bus or their combination may be choosen as
remote control
sigals.
Case study
of coordinate control takes the summation of active
power flow
in 3 different AC tie lines acquired by
Phase Measurement
Unit System (PMU) as input signal for both sides of 3 HVDCs. Eigenanalysis shows the designated coordinate control is significantly effective to the critical oscillation modes.
