因為都幾長下會分唔同時間上傳, 仲有會幾亂下... 遲下有時間會汁汁
因為本身report 都幾長, 所以我唔post 曬上黎...

我想問大家會唔會mind 我用英文, 如果有時間我再加中文
Summary
The use of an embedded system to monitor, control and protect a power system. Such functions used to be carried out on a
power system by analogue instrumentation but are now being replaced microprocessor based
relay. You will work with a power system simulator that represents the functionality of an 11kV
power system at a reduced level of voltage and current.

回復 1# franklee006

我想先了解下呢個11kV ring,請問係你自已想像出來或參考已用緊的11kV network?

係參考已用緊的11kV network, 不過原文有幾頁我廢時全部貼上... 我諗都未必有人睇

The 11kV ring distribution network consists of a primary substation and number of secondary
substations.
A typical primary 11kV substation as shown the left
figure, the power is fed into this system by 33kV/11kV
transformers arranged in delta-star configuration at the
primary substation. Two or more transformers are
normally used to feed an 11kV panel board. This board
consists of a three-phase busbar (often separated into
two main sections each of which can be fed by one of
the main transformers). Sections of cable network,
usually arranged as some form of ring, are connected
1 Note that voltages of the power system are usually given as rms line voltages. The rms phase voltage is the line voltage divided by √3.
onto this panel.  etc...............................................................

回復 12# franklee006


Pri sub 11kV  sections 是NO point ,0甘個11kV ring NO point 在那兒呢 ?

    係mock-up system 張相 你睇下
我地唔會用 11kV, 我地用 12V 做 simulation

未必有人睇?

放心啦,呢到好多高手!!至少我好有心機去睇同跟ching你學野

等我第二時見工都多樣野吹下

只可講句"小弟才疏學淺"
只可以純支援....
難得係香港地有人梗有心機寫返D作品相關野出嚟.
