请教PSCAD中PLL模块!
PSCAD中的三相PLL模块的比例、积分系数是如何确定的?有没有关于这个PI调节型PLL模块的详细资料?-%-97836-%--%-71399-%- 这两个是PI调节器的时间常数,可以根据经验进行选取,或者根据自动控制理论分析其稳定性。
帮助里有详细的模块实现 帮助里有详细的模块实现?
我看的该模块帮助写得很简略:
Three-Phase PI-Controlled Phase Locked Loop
Description
Input Parameters
Description
This component is a 3-phase, PI controlled phase locked loop, which generates a ramp signal theta that varies between 0 and 360°, synchronized or locked in phase, to the input voltage Va.
The Phase Vector Technique is used to generate the ramp. This technique exploits trigonometric multiplication identities to form an error signal that speeds up and slows down the phase-locked oscillator, to match the phase of the input. The phase error is passed as an output variable after conversion to degrees. The frequency of the input is computed and returned as an internal output parameter called Name for Tracked Frequency.
不知道你所说的帮助里有详细的模块实现是指的哪个帮助文件?
谢谢!
是的啊
锁相环 真的是很重要的啊,但是感觉很难的啊,看也看不懂的啊,寻求帮助的啊 其实一点也不难学电力不学控制等于缺了一条腿
国外EE包含若干专业 划分并不明显
相反国内专业划分过细 效果却适得其反
