无功功率对供电系统和负荷的运行都是十分重要的，电力系统网络元件的阻抗主要是电感性的。在电力系统中，粗略的说，为了输送有功功率，就要求送电端和受电端的电压有一相位差，这在相当宽的范围内可以实现；而为了输送无功功率，则要求两端电压有一幅值差，这只能在很窄的范围内实现。不仅网络元件消耗无功功率，大多数负载也需要消耗无功功率，网络元件和负载所需要的无功功率必须从网络中获得。显然，如果这些无功功率都是由发电机提供并经过长距离的传输是不合理的，也是不可能的，所以最合理的方法是在需要消耗无功功率的地方进行无功补偿。

4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to 
replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible: supports all international standard open fieldbuses and can be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
Simple engineering: configuration, commissioning and diagnostics using only the same tool CBF (Control Build F) software
