Özet
A combination of factors, including increased demand and constraints on the installation of
new power lines, is putting strain on the transmission networks that support today's electrical
systems. When a stressed system is disrupted, it is more likely that it may become unstable.
Improved transient stability is required to maintain system security since the development
of a defect should not result in the tripping of a producing unit due to loss of synchronism.
This could the system's integrity. Based on our findings, FACTS (flexible alternating current
transmission system) devices continue to exert the same amount of pressure on a
transmission network as before, causing it to make better use of its existing facilities while
still providing a enough margin of safety for stable operation. As far as current FACTS
devices go, the TCSC offers the greatest degree of flexibility in terms of boosting transient
stability. The transmission line impedance may be varied rapidly and continuously thanks to
a FACTS device connected in series. Power management on transmission lines.
Both the Power System Stabilizer and the Automatic Voltage Regulator (AVR) are
responsible for keeping an eye on the generator's output. Because of the management of the
excitation value, this combination prevents power fluctuations and maintains consistent
output power.
PSS is incapable of dampening oscillations across zones in a power system with several
equipment. The problem of coordinating a PSS and TCSC in a power system with several machines can be solved with the use of optimization algorithms. As part of this research, we
examine how changing the load on each machine affects the transient stability of two
different power systems. There are three generators and nine buses in the second power
system, whereas there is only one generator and an unlimited number of buses in the first.
Using particle swarm optimization, we investigate how best to synchronize. It is believed
that the best method for resolving the suggested synchronization control problem is to use
an objective function and the accompanying constraint equations. Within the framework of
a multi-machine power system, historical models were used to evaluate the proposed design's
feasibility under a variety of operating scenarios. Even if both PSSs and UPFCs work well
separately, the stability of the power system may be significantly weakened by external
variables such an adverse effect or poor controller contact. This is because the controllers
are unable to communicate with one another. Inter-area oscillations have been greatly
reduced as a result of the integrated architecture.
