For more details see the Operating Instructions of REG216 Numerical Generator Protection REG216 / REG216 Classic 1MRB520004-Ben Page 3 ABB Switzerland Ltd Power Technology Systems 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.
