Introduction

Laplace's equation
Laplace's equation is a partial differential equation. Partial differential equations (PDE) are a type of differential equation, i.e., a relation involving an unknown function (or functions) of several independent variables and their partial derivatives with respect to those variables. Partial differential equations are used to formulate, and thus aid the solution of, problems involving functions of several variable ....etc

Abstract

A transmission line trip during a power swing may cause instability of a power system. It is necessary to recognize the power swing from fault. Based on stability boundary, the power swing blocking relays must be set. To do that, first power swing should be analyzed. Second a way of probability of occurrence of fault must be found. Third, the critical condition under which the stability of a power system hasn’t been disturbed is recognized. Finally the settings of the power swing relays are calculated. In this paper analys ....etc
