为了满足当今新的变电站逐步要达到的各项目标的要求，已设计了这些继电器的平台。历史的发展是：保护、控制和测量功能最初是由机电式元件完成的；然后由静态元件完成；最后是由数字式设备完成。数字式设备将所有这些功能集成在一个设备内，被称为智能化电子设备（IED）。这些IED 不仅必须完成所有与保护和控制有关的功能，还要通过快速通讯，必须相互共享信息，而且要把这些信息发送到控制调度中心。这样做最多可将元件数量和接线减少70%。
F650 就属于这一类新一代的设备之一，并且能很容易地同变电站自动化系统配合使用。
intelligent field instruments is through
IART protocol or fieldbus (31.25kb profibuspa and FF Bus).
The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard),
The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application.
Popular PC and MS_ Wi ndows2000 has been widely used in various fields all over the world and has become the de facto standard computer platform
Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the
It is universal, open and easy to use, and brings great convenience for future technology upgrading and maintenance.
System engineering configuration is very convenient. The configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions
The algorithm library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large number of 3D symbols.
The system uses the same set of configuration tool software to complete the configuration and
