Turbine Operation (TO) study plan

Explain the Rankine cycle and turbine expansion process in your own words, including how enthalpy drop converts to shaft work

Derive and apply the corrected steam-flow or efficiency relationship for a single turbine stage, showing each variable's units

Identify the major turbine components (rotor, diaphragms, bearings, glands, valves) and state the function of each from memory

Sketch a simplified turbine cross-section labeling steam path, seals, and bearing locations

Calculate stage efficiency and heat rate from given inlet and exhaust conditions

Describe the lube-oil system flow path from reservoir through pumps, coolers, filters, and bearings, listing each protective device

Explain the cooling-water system layout and how loss of cooling affects bearing and oil temperatures

State the key working-fluid chemistry limits (conductivity, pH, dissolved oxygen, silica, chloride) and the consequence of exceeding each

Trace gland-seal steam and explain how seal-steam pressure imbalance causes either steam leakage or air in-leakage

List the auxiliary systems that must be proven available before a turbine roll

Sequence a cold start from turning-gear engagement through synchronization, stating the purpose of each hold point

Explain the difference between cold, warm, and hot starts and how metal temperatures change the allowable loading rate

Describe the control-system architecture (speed/load control, valve positioning, feedback loops) and identify failure modes of each loop

Interpret a startup curve relating rotor speed, shell temperature, and allowable load rate

Explain how overspeed protection, trip-and-throttle valves, and the emergency trip system function together

Diagnose the causes and correct operator responses for at least six abnormal conditions (high vibration, bearing overtemperature, water induction, loss of lube oil, high exhaust pressure, seal-steam loss)

Explain the trip logic that initiates an automatic shutdown and the actions required after a trip

Describe a controlled shutdown sequence and the conditions that justify an emergency trip instead

Differentiate between a trip, a runback, and a load rejection, and state the operator action for each

Rehearse the decision path for water-induction response using a written scenario

Explain the instrumentation used for speed, vibration, temperature, and pressure measurement and the typical failure modes of each

Describe protection-system redundancy, voting logic, and periodic proof-testing requirements

Analyze a trip event: reconstruct the sequence from alarm and trip logs and identify the first-out cause

Distinguish instrument faults from true process upsets using cross-checks between redundant channels

State the acceptance criteria for vibration and bearing temperature that trigger alarm and trip

Plan a maintenance outage: list inspection tasks for bearings, seals, valves, and rotors and sequence them logically

Explain nondestructive examination methods used on turbine components and what each detects

Identify the safety hazards of turbine work (stored energy, hot surfaces, confined space, rotating equipment) and the controls for each

State the environmental and regulatory obligations for emissions, water discharge, noise, and recordkeeping that apply to turbine operation

Describe lockout/tagout and permit-to-work requirements for isolating turbine systems

Explain generator synchronization conditions (voltage, frequency, phase angle, phase sequence) and the consequence of each being out of tolerance

Describe how the turbine governor responds to grid frequency changes and what droop means in practice

Explain reactive power, power factor, and how excitation control interacts with turbine load control

Analyze a load-rejection or islanding event and state the turbine and generator responses

Review thermodynamic efficiency calculations and connect them to actual grid dispatch decisions

Complete a full-length timed practice exam and score it by domain to identify remaining weak areas

Re-review the three lowest-scoring domains using your own summary sheets and decision tables

Recite from memory the startup, shutdown, and emergency-response sequences without reference material

Verify retention of chemistry limits, protection setpoints, and regulatory obligations with a self-made flashcard set

Build a final one-page quick-reference sheet covering formulas, setpoints, and response sequences
