This seminar explains the key factors regarding application and operation of control systems for hydro generators. Specifically, the seminar will focus on stability, frequency control (governor and automatic generation control), voltage control (exciter/AVR and joint var control), and coordination of protection with control. Drawing on the extensive experience of the presenters, the seminar is reinforced with practical examples of real world problems and solutions.

Learning Objectives

After this seminar, the attendees will understand the key factors, including grid code requirements, in application and setting of the control systems as follows:

  • Theory of speed control:
    • Specification and application of hydro turbine governors, and
    • Design and commissioning of power and frequency control systems; parallel operation of generators, gate droop, power droop, automatic generation control (AGC), grid, and isolated frequency regulation.
  • Theory of voltage control:
    • Specification and application of exciters and Automatic Voltage Regulators (AVR),
    • Design and commissioning of Voltage and Reactive Power control systems; reactive drop and droop compensation, Joint Var Control (JVC), Voltage Stability,
    • Synchronous generators and power system stability enhancing techniques, and
    • Coordination of control systems and protection systems.


Basic knowledge of 3-phase electric power systems and control systems. Basic knowledge of 3-phase large generators. Familiarity with major equipment used in generation and transmission of electrical energy. Possessing of an electrical technologist or engineering degree is preferred.

Target Audience

Electrical and mechanical engineers who are involved in the planning, design, commissioning, maintenance, and operation of hydroelectric power generation systems will benefit from participation in this seminar.
