Over/Under Voltage Protection

The F650 includes the following voltage elements:

• Phase undervoltage/overvoltage elements (each element has three individual phase undervoltage/overvoltage components)

• Auxiliary undervoltage/overvoltageelement

• Neutral overvoltage element


Following are some of the key applications where voltage elements can be used:

• Source transfer schemes

• Load shedding schemes

• Back up capacitor bank protection and control

• Backup motor protection to prevent automatic restart

F650 Logic Configuration

F650 Logic Configuration is the powerful programming logic engine that provides the ability of creating customized protection and control schemes thereby minimizing the need, and the associated costs, of auxiliary components and wiring. Using F650 Logic Configuration, the F650 can be programmed to provide required tripping logic along with custom scheme logic for auto transfer schemes (Main-Tie-Main), load shedding based on frequency, voltage and communication, loop restoration schemes, other remedial action schemes and dynamic setting group changes. F650 provides a comprehensive set of analog operands for two digital or analog inputs.


Configuration maintenance function
Configuration maintenance functions include logical configuration, download and modification, operation debugging, remote diagnosis, etc. In the early days, PLC was mainly based on ladder diagrams, while DCS was mainly based on module function diagrams. After years of development, the International Electrotechnical Commission has established five programming languages through the IEC1131-3 standard. Currently, mainstream DCS and PLC all comply with this standard and support several or all of these programming languages. From the perspective of development efficiency and program readability, module function diagrams and sequential function diagrams are increasingly becoming the main programming methods, while trapezoidal logic and structured text have become development tools for custom modules. Large PLCs are becoming more and more like DCS in terms of configuration, and the gap is gradually narrowing, while small PLCs still rely mainly on ladder diagrams.

After years of development, DCS has accumulated a large number of advanced algorithm modules. For example, the device level module of NETWORK 6000+integrates device oriented basic control and fault alarm functions in one module, and is also transmitted as a unit in network communication, greatly improving the efficiency of software development. A device pole module is equivalent to a ladder diagram logic quantity of 0.5K, and it is much more cumbersome for a PLC to complete the same function.
PLC lacks solutions in terms of downloading, modifying, running debugging, and remote diagnosis. And DCS was designed from the perspective of system needs from the beginning, with years of accumulated and comprehensive solutions. Taking NETWORK6000+DCS as an example, the system can modify control policies online or download them online. During the modification and download process, there is no impact on the normal operation of the system. NETWORK6000+DCS has comprehensive virtual DCS functions, which can not only be used for verifying configuration logic, but also be built into a complete virtual DCS connected to the model to complete system simulation and debugging. NETWORK 6000+DCS has comprehensive security measures and provides remote debugging solutions based on a wide area network.
