The Research Of The Device With Overvoltage Of Resonance Of The System In Ungrounded Neutral Point

In ungrounded systems, PT saturation result in ferroresonance is a appear frequently and work accident sort of inner overvoltage. In close a few years, PT saturation result in ferroresonance overvoltage apear frequently in HuBei ShaShi power plan, For resolve PT saturation result in ferroresonance overvoltage, cooperate with Wuhan university Though, 6Kv and 10kV antitype simulation experimentation, Progress particular research in the probability of inspire ferroresonance and the type of ferroresonance over voltage in HuBei ShaShi power plan. Educe instruct conclusion taken on HuBei ShaShi power plan electric power systems run.Forward adoptive eliminate ferroresonance measure all have definite vice in our country, So as to ferroresonance overvoltage all the time appear in fruit electricity net. This paper develop an new type absorbed energy eliminate ferroresonance machine of single chip control, composed with absorbed energy part and take count of display part and indication and 8031 give priority to control. At the same time for check the work up to snuff in some years, our design examination button. Through simulation experimentation proved that new type absorbed energy eliminate ferroresonance machine can eliminate all sorts of ferroresonance and avoid the flaw of all sorts of eliminate ferroresonance measure.
