摘要
本文叙述了一种以发挥微机硬件与软件作用的新型波形合成装置,可以模拟各种畸变波形,作为电力系统中的仪器仪表以及继电保护装置提供波形失真试验信号源。通过键盘人机对话,设置幅值、频率、初相角以及合成的波形次数,该装置可仿真产生用户所需要的波形。本装置既能作为一个质量优良的纯正弦波源(其含谐波率小于0.2%,稳定度为0.1%),又可以作为一个可控可调的谐波信号源。
This paper describes a new equipment of synthesizing harmonic for bring the software and hardware into full play. It can simulate various distortion waveforms and provide the signal source of waveform distorti experiment for the instrumentation of a power system and relay protection set. It can be study of this equipment is of great significance for making sure that the running of a power system is rreliable and the level of automatic detection. is raised up.
