10) This relates to the competency standard unit as a whole, providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance.Systems, plant and equipment may include generator cooling systems; fuel delivery systems; generator and generator auxiliary plant; generator seal oil system; generation fire protection system; boiler, turbine and unit coordinated control systems; generator circuit breaker/transformer; unit auxiliary switchboards; electricity market auto loading systems; generator excitation systems which may include- d.c. pilot excitors and amplidyne(s) control, a.c. pilot excitors and thyristor control, brushless systems, static systems, associated supervisory, control and protection equipment; Circuit breakers, field, excitor, flashing, associated supervisory, control and protection equipment; Transformers, excitation, earthing and neutral, voltage and current; and automatic voltage regulator (AVR) system.Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, national standards for plant, relevant State and federal legislation and Australian standards.Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; enterprise operating instructions; equipment and alarm manuals; dedicated computer equipment; enterprise standing instructions and plant notes; enterprise log books; market load profile forecasts; electricity market bidding information; and manufacturer’s operation and maintenance manuals.Technical and operational indicators may include stimuli (audio, smell, touch, visual), remote or local indicators and recorders, computers and alarms (visible and/or audible).Communications may be by means of telephone, two way radio, pager, computer (electronic mail) and operating logs (written or verbal).Tests may include supply change-over tests, “black” start tests and capability tests.Appropriate personnel to consult, give or receive direction may include supervisor/team leader or equivalent; other coordinators of energy production; other operating staff; technical and engineering officers or equivalent; maintenance personnel; and contractor staff.Operating environment may be remote from plant and equipment being operated; where operation is assisted by remote indicators of plant status and other parameters monitored; during night periods; during inclement or otherwise harsh weather conditions; and in wet/noisy/dusty areas.Unit operations (systems requirements) may include normal generating models and system auto frequency control mode.Faults and abnormal operating conditions may include unit trip; market distribution network disturbances; loss of station a.c. supplies; generator excitation/transformer; CB faults/malfunctions; and unit coordinated controls malfunctions.Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
