Optimization of tap settings and capacitor units with expert system on distribution system

Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers, Communications and Automation, 2002
An expert system method for discrete VAr optimization on distribution system is presented in this paper. The expert system can aid the planning engineers to make an initial feasible solution, and to decide the position of transformer tap settings and the number of capacitor units.

Line-Drop Compensator Settings for Automatic Parallel Operation of Load-Tap-Changing Transformers

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1958
From these calculations, a load voltage with an error of approximately 0.12% can be maintained at the expense of increasing the circulating current from 10.2% to 10.62%.

Method and Software Tool for Assessment of Seasonal Step-Up Transformer Optimal Tap Settings

2020
In most European countries the generators’ step-up transformers are demanded to be equipped with tap changers, explicitly or through tanϕ.-voltage requirement. Releasing the maximum available reactive power range of generator or at different voltage levels at the point of common coupling is the prime purpose of required transformers variable turns ...

Transformer Tap Setting and System Voltage Raise Impact on Optimum Planning of Static Capcitors

IEEE Transactions on Power Apparatus and Systems, 1984
Capacitor planning is based on network voltage maintenance under the normal and abnormal power system operation. The security against contingencies, the transformer tao setting and system voltage steady state operating limits together with other variables feasible range define the problem boundaries.

Probing material properties of polymeric surface layers with tapping mode AFM: Which cantilever spring constant, tapping amplitude and amplitude set point gives good image contrast and minimal surface damage?

Ultramicroscopy, 2010
A phase shift between the oscillatory motion and drive motion of an AFM-cantilever used for tapping mode AFM imaging can be related to adhesive and elastic properties of surface layers. In this study it was studied how optimal contrast between hard and soft surface layers can be achieved while minimizing the surface damage.

Optimal tap setting and VAr compensation effect on energy consumption of electrical auxiliary system of steam power plants

2002 IEEE Region 10 Conference on Computers, Communications, Control and Power Engineering. TENCOM '02. Proceedings., 2002
Reduction of energy consumption in electrical auxiliary system (EAS) of steam power plants leads to considerable energy conservation that can be fed into a network. To reach this goal, two definite suggestions i.e. tap setting of transformers and installation of reactive power compensators have been presented, and analyzed from many aspects for unit 1 ...

Use of emotional touchpoints as a method of tapping into the experience of receiving compassionate care in a hospital setting

Journal of Research in Nursing, 2009
Improving the patient and family experience in hospital and supporting people to deliver compassionate dignified care is a priority on the policy agenda in the UK. The purpose of this paper is to describe our experiences of using the method of emotional touchpoints to learn about compassionate care in hospital settings.

Tapping on the Black Box: How Is the Scoring Power of a Machine-Learning Scoring Function Dependent on the Training Set?

Journal of Chemical Information and Modeling, 2020
In recent years, protein-ligand interaction scoring functions derived through machine-learning are repeatedly reported to outperform conventional scoring functions. However, several published studies have questioned that the superior performance of machine-learning scoring functions is dependent on the overlap between the training set and the test set.

Effects of Transformer Tap Settings on the Resistance Spot Weldability of Hot-Dipped Galvanized Steel: Nugget Development Studies

SAE Technical Paper Series, 1990
<div class="htmlview paragraph">This paper is a continuation of previous work on the effects of tap setting and percent heat on the weldability of galvanized steel. A previous work dealt with changes in current range behavior. This paper considers changes in nugget development.
