    2.4 LOSS OF FIELD ELEMENT(40). MIWII1000 2 PRODUCT DESCRIPTION 2.4LOSS OF FIELD ELEMENT(40). MIWII1000 MIWII units provide a loss of field detection unit. When a generator operating at full load loses excitation, it starts to operate as an induction generator, rotating at a higher speed than the synchronous speed. In this situation, the generator is still providing active power to the system, but it starts consuming reactive power from the system to maintain its excitation.

The main source of electrostatic discharges is human body, especially under low humidity conditions, with carpet floors or isolating shoes. If such conditions are present special care should be taken while manipulating MIWII modules.

  • Page 46: Mounting

    3.1 DESCRIPTION 3 HARDWARE 3.1.1 MOUNTING The unit is designed for semi-flush mounting. The relay is secured to the panel with the 4 M6 screws provided with the unit. This allows the user access to the front keypad, display and communication port. The wiring is at the rear of the unit. The drilling dimensions are shown on the drilling dimension diagram.

  • Page 47: Rear Description

    3 HARDWARE 3.1 DESCRIPTION 3.1.2 REAR DESCRIPTION The relay is wired through the terminal blocks located at the rear of the unit. In this terminal board, current terminals are shorted two-by-two when the transformer module is extracted, so that the CT secondary never remains open. Figure 3–3: REAR VIEW The magnetic module with the CTs is already connected to a female connector screwed to the case that incorporates shorting bars in the current inputs, so that it can be extracted without the need to short-circuit the current externally.

    “A” and “B”, although many devices use terminals named “+” and “-“. As a general rule, terminals “A” should be connected to terminals “-“, and terminals “B” to “+”. There are exceptions to this rule, such as the GE ALPS and DDS family of relays.

  • Page 59: Communications

    The ENERVISTA MII SETUP software package uses only ModBus protocols, and is designed to communicate with a single relay at a time. GE Multilin offers different communication software packages, such as GE-POWER and enerVista, which can be used to communicate simultaneously with several relays.

    4.1 ENERVISTA MII SETUP SOFTWARE 4 COMMUNICATIONS 4.1.2 STARTING COMMUNICATION Before the physical connection to the relay, it is important that the user reviews the safety instructions detailed in section 1. This section explains the importance of connecting both relay ground terminal and computer to a good grounding. Otherwise, communication may not be possible, or the relay and/or the computer could be damaged.

  • Page 159: Installation And Maintenance

    10 INSTALLATION AND MAINTENANCE 10.1 INSTALLATION 10 INSTALLATION AND MAINTENANCE 10.1 INSTALLATION The relay should be installed in a clean, dry and dust-free place, with no vibrations. It should also be well lit to facilitate inspection and testing. Operational conditions as defined in section 3 must not be exceeded in any case. The relay should be mounted on a vertical surface.
  • Page 160 10.2 GROUND CONNECTION AND DISTURBANCES SUPPRESSION 10 INSTALLATION AND MAINTENANCE 10.2GROUND CONNECTION AND DISTURBANCES SUPPRESSION Threaded plug labelled as GND (refer to 1.3) should be correctly grounded, so that the disturbance suppression circuits in the system work correctly. This connection should be as short as possible (preferably 25 cm or less) to guarantee maximum protection.
  • Page 161 10 INSTALLATION AND MAINTENANCE 10.3 MAINTENANCE 10.3MAINTENANCE Given the important role that the protection relays play in the operation of any installation, a periodical program of tests is highly recommended. The unit incorporates built-in diagnostic functions that permit immediate identification with only the aid of the keypad and display, the detection of some of the most likely circuit failures.
  • Page 162 10.4 CLEANING INSTRUCTIONS 10 INSTALLATION AND MAINTENANCE 10.4CLEANING INSTRUCTIONS In case of detecting accumulated pollution, the unit can be cleaned with a clean cloth, either dry or slightly dampened with a cleaner containing alcohol. Abrasive cleaners must be avoided, as these can damage the metallic surface or the electrical connection elements. 10-4 MIWII Directional Power Protection System GEK-113308...

    APPENDIX A A.1 GENERAL PRINCIPLE OF OPERATION APPENDIX A HARMONIC FILTERINGA.1GENERAL PRINCIPLE OF OPERATION The present document intends to give an overview on how the relay deals with analog signals, in order to help determine whether the relay is appropriate for certain applications. MIWII relays, as the rest of our digital relays, are based on the following functional diagram: Figure A–1: FUNCTIONAL DIAGRAM Each of these blocks has its own functionality inside the general operation of the unit, as follows:...

  • Page 172: Digital Filter

    A.2 DIGITAL FILTER APPENDIX A A.2DIGITAL FILTER The first operation performed by the CPU with the voltage and/or current signal samples is the DFT. The Discrete Fourier Transformation consists in decomposing a signal into a series of sinusoidal signals with frequencies that are multiples of the fundamental frequency.
  • Page 173 APPENDIX A A.2 DIGITAL FILTER Figure A–4: the measurements can experience small variations for frequencies that are not the fundamental and its harmonics, as the measure varies for these frequencies. As an example, we can see in the next figure how a relay measure varies when it is set to 50 Hz, and it is being applied 60 Hz.

  • Page 174: Measure At Frequencies Below The Rated Frequency

    A.3 MEASURE AT FREQUENCIES BELOW THE RATED FREQUENCY (FREQUENCY TRACKING) APPENDIX A A.3MEASURE AT FREQUENCIES BELOW THE RATED FREQUENCY (FREQUENCY TRACKING) As already mentioned, the digital filter is related to the fundamental frequency, so higher multiple frequency values are annulled During the start-up of generators, the voltage frequency in terminals and currents that can appear in the event of a fault, will depend on the machine speed.
