Self-monitoring and testing facilities The self-monitoring and testing routine philosophy of the REG216 can be divided into following sections: • Self-monitoring • Parameter viewing facilities • Injection testing with separate test equipment. Self-monitoring The self-monitoring and testing routine philosophy is quite different from conventional testing techniques. Whilst the previous practice in protection was to maintain availability through comprehensive periodic testing. REG216 does this continuously by taking full advantage of digital and data bus technology. The self-monitoring functions have two elements: • Continuous self-monitoring by hardware • Cyclically executed testing routines, mainly by software. Numerical Generator Protection REG216 / REG216 Classic 1MRB520004-Ben Page 7 ABB Switzerland Ltd Power Technology Systems Testing Viewing protection measurements One feature of the REG216 is the provision to view various operating measurements. This together with the self-monitoring functions replaces the periodic injection testing necessary with conventional protection equipment. The following data can be viewed: a) The system values as measured by all protection functions. The corresponding functions do not have to have picked up for this purpose. b) Analog inputs. The amplitudes, frequency and phase relationships of all the analog inputs can be viewed without jeopardizing the operation of the protection functions. c) Digital input and output signals. The status of each signal can be viewed. Apart from the self-monitoring routines, the fact that the measurement data can be viewed all the way from the input transformers to the digital signals also confirms the correct functioning of the digital processors and the data bus. Using software HMI „Test functions“ The desired protective function may be selected from the list of available active functions. The test operation is based on simulated numerical values. One or more channels may be selected for testing the tripping or signalling outputs. The test function is mainly used for commissioning purposes when the system is out of service. Redundancy Hardware and software redundancy is adapted to the functional requirements. Two independent groups of protection functions are accommodated in either two separate hardware racks or in only one rack, but with two completely independent hardware groups. Injection testing A 100% test of the system can be carried out by injecting test voltages and currents using, for example, a test set type OMICRON. Provision is made for injection testing with a test set at the terminals of the input transformer assembly 216GW62. The terminals enable primary system PT circuits to be interrupted and CTs to be short-circuited.
