Who Needs An AVC? 誰需要AVC ?

Factories, facilities and commercial operations that
are dependant on a good quality power supply so
they can produce quality products without
interruption need the ABB AVC.

高度要求電力品質的工廠、設備與公司行號。當這
些客戶的連續生產受到中斷時，產品品質會受到很
大影響。這些場合非常需要AVC解決方案。

Cause of Power Quality Problems 電力品質問題的起因

The Utility attempts to supply sag and swell free power to the end user. However even with
extensive maintenance programs the Utility cannot prevent power quality problems from
affecting the end user.
盡管台電耗費許多人力和大筆金錢維護電力網路，嘗試提供穏定電壓給用戶。仍無法避免電力品
質問題造成用戶的困擾。

Boost Transformer Internally Bypassed

When the AVC is not online the boost transformer primary must be short
circuited

Online means the AVC is running providing voltage regulation and sag
correction

When internally bypassed the boost transformer “from an electrical
perspective” appears as a reactor (inductor) in series with the load

PCS100 UPS-I, Industrial UPS
There is a solution
© ABB Group
April 13, 2015 | Slide 34

The PCS100 UPS-I is the ideal solution
where very deep sags or short term
power outages are a problem

The PCS100 UPS-I uses energy
storage coupled through an inverter to
allow the downstream load to ride
through very deep sags and short term
outages

The PCS100 UPS-I is an offline system.
It is inactive unless the voltage falls by
10% - 13%. This enables it to be very
efficient, up to 99%
