A modern energy management system (EMS) that has been in operation at the China Light and Power Company (CLP) in Hong Kong for over five years is described. The EMS is located in a building specifically designed for a system control center and also includes facilities for support staff. Although the EMS was designed to monitor and control the CLP transmission and generation network, the control center includes other auxiliary and support facilities, such as an operator training simulator, distribution control, maintenance workshops, communication facilities, power supplies and personnel offices. An introductory section of the paper explains the basis for the installation of the EMS. This is followed by discussions which explain the scope of the control center, the unique operational conditions addressed, unique control problems addressed, applications, and changeover experiences. The rapid growth of the service area and experience with this control center have led to an upgrading planned for completion in 1991. The justification and scope of this upgrading are presented. Operator training is a continuing process at the CLP control center. This activity has been incorporated into the overall configuration and into the plan for the EMS. Its execution is described
