Energy control system - An advanced approach for TransAlta utilities
TransAlta Utilities, the largest investor owned electric utility in Canada, is implementing an advanced Energy Control System to be located in Calgary, Alberta. This Energy Control System (ECS) consists of four large-scale processors configured as a Main Applications Computer (MAC) and a Security Applications Computer (SAC) with the remaining two processors in a dual redundant mode with the MAC and SAC. The system includes MMI equipment and advanced SCADA interfacing hardware which supports the Sequence of Events (SOE) function. This paper provides a functional description of the overall Energy Control System configuration and the software provided. Some of the advanced functions provided include a Decoupled State Estimator, a Decoupled Operators Load Flow, a Contingency Evaluation Program which allows enhanced flexibility in defining contingencies, a constrained VAR dispatch program which will provide control advisories to the operator or to the Automatic VAR Control program to implement the changes required, and an Operators Training System which includes simulation of the power system relays and cyclic non-conforming loads. The interrelationship of the programs and subsystems is discussed, as well as the Man Machine Interface provided to effectively use them.
