Working principle

Input working principle: When an external device (such as a sensor) generates a digital signal, the signal is transmitted to the ABB UNS0874A digital I/O card through the input channel. The input channel first electrically isolates the signal to prevent external interference signals from entering the internal circuit of the card. At the same time, the signal undergoes level conversion to convert it into a standard level signal that can be processed internally by the card. After isolation and conversion, the signal enters the input buffer, which buffers and preprocesses the signal before transmitting it to the data processing unit. The data processing unit analyzes and judges the received signal, removes interference signals, determines the logical state of the signal (high or low), and stores the processed signal in the input data register, waiting for the system to read.

Output working principle: When the system needs to send control instructions to external executing devices (such as relays, solenoid valves), the control signal is first written in digital form into the output data register. The signal in the output data register is processed and converted by the data processing unit into a signal form suitable for driving external loads. Then the signal is transmitted to the output driver, which amplifies the signal to meet the driving requirements of external loads. The amplified signal is transmitted to the external execution device through the output channel to control the device’s actions. At the same time, the output channel also has electrical isolation function to prevent the internal circuit of the card from being affected by electrical interference from external loads.

• Long-term stability

• Communication and coordination with station control

• Two design versions available; REG216 / REG216 Classic

Application

The REG216 is intended for the protection of generators and block transformers.

The modular hardware and software design allows an extremely flexible installation.

Simplicity of adaption to the size of the primary system and the desired protection schemes are achieved through the combination of a software library and hardware modules.

Economic solutions can thus be achieved in the full range of applications for which it is intended.

The REG216 software system offers a library of protective functions.

Functions suitable for generator and transformer protection are listed in the table below.

Different degrees of redundancy can be selected.

Availability and reliability of the protection can be chosen to suit the application by duplicating e.g. auxiliary supply units of the whole system.

Standard interfaces make REG216 compatible with different process control systems.

Data exchange with higher process control levels are possible, e.g. one-way reporting of digital states and events, measured values and protection parameters.

REG216 and REG216 Classic differ with regard to the binary process connection:REG216 uses the E/A-module 216GD61a.

The REG216 Classic uses the modules 216GE61 / 216GA61 and 216GA62.

Protection functions

All protection functions required for the stand-alone protection of generators, power transformers and feeders are available.

The system therefore replaces several relays of a conventional protection scheme for such power system equipment.

The table on page 2 gives a survey of the most significant protection functions.

The desired protection functions to suit the particular application can simply be selected from a comprehensive library using the personal computer. 

​No knowledge of computer programming is required.

All setting ranges are extremely wide to make the protection functions suitable for a multitude of applications.

The following main parameters can be set:

• Allocation of processing units

• Input channel or channels

• Pick-up setting

• Time delay

• Definition of the operating characteristic

• Tripping logic

• Control signal logic.

Setting a corresponding parameter enables the protection functions to be “connected” to particular input channels.

Digital input and output signals can also be internally combined logically:

• The tripping outputs of each protection function can be assigned to channels of the tripping auxiliary relay assembly in a manner corresponding to a matrix

• The pick-up and tripping signals can be assigned to the channels of the signalling auxiliary relay assembly.

• Provision is available for blocking each protection function with a digital signal

(e.g. digital inputs or by using the tripping signal of another protection function).

• External signals applied to the digital inputs can be processed in any desired fashion.

• Digital signals can be combined to perform logical functions e.g. 

External enabling or blocking signals with the output signals of an internal protection function and then used to block one of the other protection functions.

Remote in- and outputs (RIO580)

Using the process bus type MVB, remote in and output units 500RIO11 can be connected to the REG216 terminals.

The input and out put channels can be extended to a large number by using the RIO580 remote input/output system.

Installing 500RIO11 I/O units close to the process reduces the wiring dramati cally, since they are accessible via fibre optic link from the REG216 terminals.

Analog signals can also be connected to the system via the 500AXM11 from the RIO580

family:

• DC current 4…20 mA

0…20 mA-20…20 mA

• DC voltage 0…10 V-10…10 V

• Temp. sensor Pt100, Pt250, Pt1000,

Ni100, Ni250, Ni1000.

Hardware

The REG216 equipment comprises two main  assemblies which are physically separated from each other and linked by standard prefabricated screened cables:

• Interfaces to the primary system (CTs, PTs and auxiliary relays), which provide DC isolation and a barrier to electromagnetic interference

• Parallel bus and associated electronic units (e.g. analog inputs and data processors/ for signal conditioning and processing.

The complete protection scheme comprises relatively few hardware modules allowing subsequent expansion of electronic units and the interfaces. 21 units of rack space is avail able per equipment frame
