Pitch Control
Pitch Control is a crucial system in modern wind turbines that helps control how much power they produce. Think of it like adjusting the angle of umbrella in the wind - the system changes the angle of the turbine blades to catch more or less wind as needed. This helps protect the turbine in very high winds and ensures it produces the right amount of electricity in normal conditions. When you see this term in resumes, it usually refers to experience with either maintaining these systems, programming them, or designing improvements to make wind turbines more efficient and safer.

Example Interview Questions
Senior Level Questions
Q: How would you handle a situation where multiple turbines are showing pitch control errors during high winds?
Expected Answer: A senior technician should discuss safety protocols, diagnostic procedures, prioritization based on severity, and coordination with the control room. They should mention checking both mechanical and electrical systems, and explain how weather conditions impact troubleshooting approaches.
Q: What strategies would you implement to improve pitch control system reliability across a wind farm?
Expected Answer: Should discuss preventive maintenance programs, data analysis for predicting failures, staff training needs, and coordination with manufacturers for updates or improvements. Should also mention documentation and tracking of common issues.
Mid Level Questions
Q: Explain how you would diagnose a pitch control system that's operating erratically.
Expected Answer: Should be able to describe the step-by-step troubleshooting process, including checking mechanical components, electrical systems, and control software. Should mention safety procedures and proper documentation.
Q: What maintenance procedures are essential for pitch control systems?
Expected Answer: Should discuss regular inspection points, lubrication requirements, electrical checks, and calibration procedures. Should understand maintenance scheduling and documentation requirements.
Junior Level Questions
Q: What are the basic components of a pitch control system?
Expected Answer: Should be able to identify main parts like motors, sensors, control unit, and mechanical linkages. Basic understanding of how these components work together to adjust blade angles.
Q: What safety procedures do you follow when working with pitch control systems?
Expected Answer: Should demonstrate knowledge of lockout/tagout procedures, personal protective equipment requirements, and basic safety protocols for working at heights and with electrical systems.
