Abstract Transmission lines are essential components of electric power grids. Diverse power system applications and simulation based studies require transmission line parameters including series resistance, reactance, and shunt susceptance, and accurate parameters are pivotal in ensuring the accuracy of analyses and reliable system operation. Commercial software packages for performing power system studies usually have their own databases that store the power system model including line parameters. When there is a physical system model change, the corresponding component in the database of the software packages will need to be modified. Manually updating line parameters are tedious and error-prone. This paper proposes a solution for streamlining the calculation of line parameters and updating of their values in respective software databases. The algorithms used for calculating the values of line parameters are described. The software developed for implementing the solution is described, and typical results are presented. The proposed solution is developed for a utility and has a potential to be put into use by other utilities.

A design of electronic laser harp based on SCM (the abbreviation for single chip microcomputer) is proposed. It adopts the semiconductor laser transmitter and the receiving tube as a sensor, and uses the laser transmitter emits beams to imitate the 8 strings of harp. The main control chip STC89C52RC collects and processes the signal from receiving tube circuit, then STC89C52RC outputs special signal to produce sound of harp by audio. Compared with the traditional method, this design greatly enhances the anti-interference ability of the system, and it owns a certain degree of innovation and creation in not only the form of performance but also design proposal of system.
