A workload model representative of static and dynamic characteristics

Acta Informatica, 1986
A technique to implement a workload model that must be representative of both static and dynamic characteristics of a workload is presented. The main goal of this work is the construction of a representative and compact workload model. The approach taken is first to assign the set of workload components to classes having homogeneous static (i.e., load-

Dynamic Modeling of Kaplan Turbines Including Flow Rate and Efficiency Static Characteristics

IEEE Transactions on Power Systems, 2019
Models for Kaplan turbines usually assume the runner blades always follow the optimum efficiency relationship, which is not true during transient responses. This misrepresentation can lead to incorrect analysis of system stability.

Experimental Investigation of Static Load Characteristics

Advanced Materials Research, 2014
It is common practice to use 2nd order polynomial load model for steady-state power flow calculation. The paper describes the experiment for obtaining static load characteristics and the technique for identifying coefficients of the load model based on remote metering system data.

Simulation on Static and Dynamic Characteristics of Servovalve

Applied Mechanics and Materials, 2012
In this paper, we build a simulation model of the two stage flapper-nozzle electro hydraulic servovalve with the hydraulic component design libraries and the AMESet secondary development of modeling in AMESim simulation environment. By adjusting the parameters of the model, the performance of the servovalve were analyzed.

One-dimensional static sheath characteristics

Journal of Applied Physics, 1982
The boundary layer between an electrode biased to a large negative potential (relative to the electron temperature eφ≫kTe ) and a collisionless argon plasma (n∼1×109 cm−3, kTe ∼2.5 eV) was studied using Langmuir probes. A simple model based on Child’s law, including finite electron temperature effects, was fit to data obtained from both cold and ...
