Power-generation controls

Multi-generator power-station control systems.

Ultima Control engineers practical control systems for sites where several diesel generators need to work together reliably, safely and clearly for operators.

Control architecture

Coordinating generator controllers, PLCs, switchgear and SCADA

A multi-generator site needs more than standalone generator controllers. The site control layer must manage run requests, generator availability, breaker status, load demand, operating priorities, alarms, trips and operator decisions.

  • Plant master PLC or supervisory control logic
  • Generator controller integration and operating mode management
  • Bus, breaker, protection and switchgear status interfaces
  • Alarm philosophy, event recording, operator screens and trend data

Typical requirements

What the control system needs to decide

When to start and stop sets

Run sequencing based on load, generator availability, maintenance status, operator requests and required reserve.

How to parallel safely

Interfaces for synchronising, breaker close permissives, electrical status, protection state and system interlocks.

How to inform operators

SCADA and HMI screens that show plant state, running priorities, alarms, trips, trends and recovery actions.
