2014 System Operator Conference 18 INTERACTING WITH FINIST Operating Training Simulator

2014 System Operator Conference 19 Interface to the OTS (“Operator’s Workplace”) Icon you will see on the computer’s desktop Your Facilitator Team will start the OTS and initiate all events. You may be instructed to open the OWP icon to begin the drill, or OWP may already be open on your laptop. Make sure the clock in the upper right is running!

2014 System Operator Conference 38 AGC Modes Generation costs may be changed at any time and this may make AGC use another station If regulating station goes offline, the next lowest generator cost station becomes the regulating unit

2014 System Operator Conference 39 AGC Modes A generator can be in the following active generation modes: –AGC – automatic generation control - ACE control –Droop – initial mode, follows generation schedule –LFC – load frequency control, frequency regulation –Manual – fixed active generation value (manually entered) –Offline – generator is offline

2014 System Operator Conference 40 Generator Auxiliaries Generator auxiliaries – located on station one-line diagrams and Generation Control Display. Auxiliaries must be energized for generator to start and generator will trip if auxiliaries are de- energized. Can start generator without auxiliaries with blackstart option.

2014 System Operator Conference 52 Starting Generators To start a generator it needs to be connected to at least one load. This load may or may not be its own auxiliaries Started generator immediately generates power equal to the load but no more than 5% of maximum generation Load Frequency Generation The generator works for the first 20 seconds despite frequency and voltage conditions to allow operator to match island load and generation
