SYN3000
Description
4. Design Features 4.1. Optimum Plant Conformity 4.1.1. 5+1 Synchronizing Modes To apply the SYN3000 to all required plant configurations the relay is provided with 5 synchronizing operating modes. From the synchronizing mode selected the corresponding related settings have to be configured. A further, sixth, synchronizing mode is provided for measuring the circuit breaker closing time. Mode 1: Mode 2: Mode 3:
Mode 4: Mode 5: Mode 6:
Generator to bus bar or power line Synchronous or asynchronous power systems or lines Synchronous or asynchronous power systems or lines similar to mode 2, however with additional dead line or dead bus charging Synchronizing check for manual closing operations Fast automatic transfer of bus bar systems Measuring of the circuit breaker closing time
4.1.2. 2 or 10 Selection Inputs To optimise plant performance the SYN3000 is equipped with 10 selection input and an additional selection input for fast automatic bus bar transfer operations. Thus it is possible to apply a single relay to several synchronizing control circuits, e.g. Unit 1, Unit 2, etc., and/or synchronizing modes to the very same synchronizing control location, i.e. Unit synchronizing to bus bar system, synchronizing check function, etc. For each of the selection inputs specific parameter setting values can be configured, i.e. synchronizing mode, voltage level and frequency level limits, permissible voltage and frequency difference, CB closing time, i.e. CB dead time compensation, etc. When selecting a selection input, the corresponding setting parameters are loaded from the internal memory and the synchronizing operation is performed according to these parameters. Simultaneously, it must be ensured that the external control circuit is applying the correct running and incoming voltages to the SYN3000 and to connect the SYN3000 control outputs to the corresponding equipment, e.g. circuit breaker closing coil and speed- and voltage regulator. 4.1.3. Flexible Installation The SYN3000 is produced in the 19" rack housing technique with following possibilities for mounting: Mounting into an existing 19" rack Flush panel mounting When installing the relay into an existing 19" rack the space required is half a rack, i.e. two relays can be mounted into a single rack.
