大型发电机功角的微机测量系统

The Generator Power Angle Measurement System Based on Microcomputer

功角 δ在电力系统稳定问题的研究中占用特别重要的地位。本文所介绍的发电机功角微机测量系统利用 80 C1 96KB单片机进行测量和计算 ,通过系统机与单片机的串行通信 ,进行实时功角动态曲线及发电机运行参数的显示。文中还介绍了单片机与系统机的通信及用 VB5.

Generator power angle is very important in the study of power system stability.In this paper,the design method of the generator power angle measurement system based on microcomputer is presented.The measurement and calculation are achieved by using single-chip microcomputer (SCM) 80C196KB.Via the serial communication between the SCM and PC,PC can show the active curve of the real time power angle and operating parameters of the generator.Also,the method of the communication between the SCM and PC and the drawing active curve of the power angle by VB5.0 are introduced.
