Optimization of zero-sequence voltage compensation for zero-sequence directional elements

Electric Power Systems Research, 2021
Abstract Compensating zero-sequence voltage measured is an effective measure to improve the sensitivity of zero-sequence directional overcurrent protections. However, when applied to double circuit power supply system, it may lead to misjudgment of zero-sequence directional elements.

New Sequences with Zero Autocorrelation

Problems of Information Transmission, 2002
The authors give a new construction method for unimodular delta-correlated sequences of length \(p\) (a prime). This method uses so-called Gauss periods. In the case \(p=3f+1\) it is shown that the elements are defined by roots of a polynomial of degree 12 over \(\mathbb{Z}\) (the integers) for one family and by roots of a polynomial of degree 6 for ...

Generalized zero-sequence and anti-zero-sequence performance of induction machines

Archiv für Elektrotechnik, 1981
The present paper derives a new general zero-sequence steady state ladder equivalent circuit of threephase induction machines where zero-sequence currents can simultaneously flow in both the stator and rotor windings. A general expression for the zero-sequence torque is also derived.

Zero sequences for bergman spaces

Complex Variables, Theory and Application: An International Journal, 1996
Let Z be a sequence of points in the unit disk. For a variety of analytic function spaces, it is shown that the properties of the function completely determine whether Z is a zero sequence for the given space. For example, if A -n= {f analytic in D f(z)(1-|z|2)n then Z is a zero sequence for A −n if and only if kZ(z)−nlog[1/(1-|z|2)] has a harmonic ...
