A number of different protection functions are provided in the software permanently stored within the RE. 216 system. The functions required to protect a specific plant can be individually selected, activated and set. A particular protection function may be used several times in different protection schemes. How the signals are to be processed by the protection for the plant in question such as the assignment of tripping, signalling and logic signals to the various inputs and outputs is also determined by appropriately configuring the software. The system hardware is modular in structure.
The number of electronic devices and I/O units actually installed, for example, to increase the number of protection functions or for purposes of redundancy, can vary according to the requirements of the particular plant. Because of its modular design and the possibility of selecting protection and other functions by configuring the software, the generator protection REG 216 can be adapted for the protection of small, medium and large generators as well as large motors, power transformers and feeders, while the control unit REC 216 can perform data acquisition and control and supervision functions in medium and high-voltage substations.
A general description of the system and the electronic devices and I/O units installed and the corresponding technical data are to be found in data sheet 1MRB520004-Ben “Type REG 216 and Type REG 216 Compact Generator Protection”. Each RE. 216 protection system is engineered to fulfil the particular requirements of the plant concerned. A specific set of diagrams is provided for each installation, which defines the system with respect to the electronic devices and I/O units installed, their locations and the internal wiring. The set of plant diagrams includes: single-line diagram of the protection: complete representation of the plant showing the c.t. and v.t. connections to the protection. standard cable connections: block diagram showing the protection equipment cabling (electronic equipment racks to I/O units).
protection cubicle layout: installation and locations of the electronic equipment and I/O units. electronic rack layout: equipment locations within a rack. measurement circuits (three-phase plant diagram): connection of the c.t’s and v.t’s to the protection.
auxiliary supply: external connection and internal distribution of the auxiliary d.c. voltage supply.
I/O signals: external connection and internal wiring of the tripping and signalling outputs and the external input signals
