The Advanced Photon Source (APS) booster ramp cycle is completed within 250ms and repeated at 2Hz. Separate phasecontrolled power supplies deliver current to each of the dipole, quadrupole, and sextupole magnet families. Tracking requirements are particularly challenging because of the fast (non-resonant) ramp. In order to meet the requirements, both conventional regulation and cycle-to-cycle a...

nowadays, energy plays an important role in the economic and community development of country. consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. among the different power generation technologies, steam power plants make a significant contribution to power generation in iran, with a share of 47 % of electricity g...

In this study, effect of energy price on the development of a biomass gasification-solid oxide fuel cell-gas turbine hybrid power plant has been considered. Although, these hybrid systems have been studied based on sustainable approaches, economic aspects, specifically conventional energy prices, which are the principal bottleneck for the development of these new power generators, have attracte...

Power plants with complex technology have various gradations in design process so that this level in the current time by maintaining the goals of sustainability and sustainable development have a critical importance. These buildings require to be sustainable according to their complexity to provide the finance and discrete budgets for functional needs, meanwhile to design solutions to avoid cre...

This paper describes a set of results of detecting nonlinear phenomena appearing in a turbine generator power system with series-capacitor compensation. The analysis was based on the Floquet theory as well as t h e Hopf Bifurcation theorem. After t he first Hopf bifurcation, t he stable limit cycle bifurcates t o a stable torus and a n unstable limit cycle which connects to a stable limit cycle...

A new method for the nonexistence of limit cycles of the planar system including a generalized Liénard-type system is introduced. It is given by constructing a curve with some invariance defined on a half-open interval and has useful powers for the case which the equilibrium point is stable specially. Moreover, it is also applied to systems with several equilibrium points. It shall be shown tha...

Input current distortion in the vicinity of input voltage zero crossing of Boost single-phase active power factor corrected rectifier in high line frequency is studied based on one cycle control method in this paper. The current loop model and input admittance model of active power correction based on one cycle control is particularly analyzed. The results point out that its equivalent power st...

In this paper a multi-variable LPV/H∞ control approach is applied to design a strategy for power source coordination within a multi-source energy system. Three different kinds of power sources – fuel cell, battery and ultracapacitor – compose the power supply system of an electric vehicle. All sources are current-controlled and paralleled together with their associated DC-DC converters on a com...
