Power system plays a very important role in the transmission lines , it is a carrier of the power transmission , and power frequency of the transmission line parameters also plays an indispensable role in the calculation of the power system , for example , the power flow calculation stability calculation , the short-circuit current calculation . With the continuous development of the power system , the transmission lines , the line corridor , the mutual inductance line increasing number , there is a coupling of the mutual inductance between the lines , the traditional method of measurement has been unable to meet the measurement needs , so to seek new methods of measurement becomes particularly important. In this paper, based on a comprehensive comparison Transmission Line frequency parameter measurement method , transmission line power frequency parameter measurement method based on synchronous information detailed comparative analysis ; Simpower system module to use in the MATLAB environment to build a single- back and double back to the transmission line model , simulation tests ; introduction of a transmission line -frequency parameter algorithm robustness concept , elected robust comparison of each algorithm , higher measurement accuracy , stability measurements by calculating method - based on the transmission line equation and coupled transmission line equation - based method to verify the selected algorithm of the measurement accuracy ; Finally, the use of the Microsoft Visual C # language were this kind of algorithm of the software to achieve , the software not only can achieve data calculation function , also connected with the database , data storage , query and other functions can be achieved .
