Download electric power quality practice solution
Today, in this post, for you, dear users of the MagicFile website, we have prepared a complete project of electric power quality practice for download, which is as follows:
This project also has emulator files that are located inside the download file
Exercise 1 (Parallel Resonance)
مي دانيم در رزونانس موازي از رکتيفاير هارمونيک وارد ميشود.
در شبکه تک خطي يک کارخانه که به صورت شکل زير در نرم افزار متلب شبيه سازي کرديم:
In this simulation, we have two busbars, before the 1st busbar, there is a 220/33KV transformer with YY connection, and before the second busbar, there is a 6.6KV/33V transformer. The complete specifications of each are given in the transformer. .
به هر يک از باس بار ها يکسو کننده 6 پالسه 15 MW ايجاد هارمونيک مي کند.
به باس 1 يک بار 25 MW- 0.8 lag و يک خازن 8.4 MVAR متصل مي باشد.
به باس 2 نيز يک بار 15 MW- 0.8 lag و يک خازن 5 MVAR متصل مي باشد.
After performing the simulation, we can see the voltage and current of each of them with the scopes that we put in the bus bars.
Exercise 2 (Series Resonance) (Series Resonance with Correction Capacitor)
We know that in series resonance harmonics are introduced from the source! Here we select and adjust the source so that it has harmonics! For this purpose, we go to Simscape>SimPowerSystems>Specialized Technology>Electrical Sources>Three-Phase Programmable voltage Source and this We select the source and we can adjust its harmonic.
و از قسمت : Simscape>SimPowerSystems>Specialized Technology>Mesurment> three-phase voltage V-I measurements. باس بار را ادد مي کنيم.
بقيه بلوک ها نيز به همين ترتيب اضافه مي گردند.
مدار را مانند شکل زير در متلب شبيه سازي مي کنيم:
Exercise 3 (without filter) (with filter)
بدون فيلتر:
مدار را مانند شکل زير در نرم افزار متلب شبيه سازي مي کنيم:
شبکه متشکل از منبع –ترانس-باس –بار و رکتيفاير که شبکه را آلوده مي کند!حال با اسکوپ نمودار جريان و ولتاژ باس را مشاهده مي کنيم:
ولتاژ باس :
