when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...
this paper describes an optimal design for multivariable pi controller with a high gain structure for an irregular system by genetic algorithm. pi controllers with a high gain structure leads to the asymptotic decomposition of the fast and slow modes in the closed loop system that have unique characteristics. the slow modes are asymptotically uncontrollable and unobservable; therefore, they hav...
The Phase Difference Measurement Module Development for Amplitude Modulated Range Measurement System
The transient response of passivated metallic electrode system under potential step was analyzed based on a linear model, and a technique for calculating the parameters characterizing the growth and dissolution of passive film was proposed. It is believed that the information which is expected to be gained from the impedance measurement can be obtained by this technique and that this technique ...
Measuring QoS in the internet today is difficult as notions of what constitutes QoS vary. Service Level Agreements between customers and network service providers are often poorly defined. The most workable SLAs currently are defined in terms of how long packets may take to travel from some host to another host, and what acceptable levels of packet loss are. This paper presents a direct compari...
