Application of Multi-function Measure Control Analyzing Device in Electric Distribution

With the rapid development of computer technology, many kinds of monitor and analysis devices such as power quality monitor, fault record, fault detection and other device can be integrated into one device by a computer for electric distribution. And it will look very expedient and can complete all of the work in electric distribution. In this paper, a kind of method to design such multifunctional device called multi-function measure control analyzing device employed in electric distribution will be introduced. And a new algorithm using the fractal number of phase voltages and phase currents is presented for power grid monitor detection and fault line selection. The apparatus we have developed operates very well in electric distribution. And the application results show that this system is very applicable and can be used with great validity in dynamic monitoring fault diagnosis and trouble removal.
