Design The design of the System Control Centre has taken into account its operational needs with special consideration for human factors The System Control Centre has two major control functions ndash ldquoGeneration and Transmission Controlrdquo and ldquoDistribution Controlrdquo

ldquoGeneration and Transmission Controlrdquo monitors and controls the generation and

transmission systems including the submarine cable circuits interconnected with CLP Power Hong Kong Ltd through the Energy Management System (EMS)

ldquoDistribution Controlrdquo monitors and controls the distribution network via the Distribution Management System (DMS)

設計系統控制中心在設計上兼顧了人為因素和操作上的

需要系統控制中心的兩個主要控制功能包括調控

發電與輸電及調控配電的工作

港燈的發電及輸電系統（包括與中華電力的聯網

安排）是透過能源管理系統 (EMS)負責監控而

配電網的控制工作則由配電管理系統 (DMS)負責

監控

System Overview

The EMS and DMS that employ Siemens EMPOWER Spectrum systems with a distributed open system architecture were commissioned in 1999 with their hardware subsequently upgraded in 2008 The EMPOWER Spectrum uses state-of-the-art technology and is characterised by easy upgrading and extension Both the EMS and DMS are built with full redundancy for all hardware including LAN to ensure that no function is lost due to a single component failure

In addition to the normal supervisory control and data acquisition (SCADA) functions the systems also feature numerous special automatic control functions and advanced applications Besides automating routine control functions to improve operational efficiency these features provide System Control Engineers with analytical reports on the state of the real time power system as well as what will happen in case of contingencies

Man-Machine Interfaces (MMI)

All the user consoles in the System Control Centre have multiple LCD monitors to allow concurrent display of information needed in operations Each EMS and DMS system also has its own large wall display unit to project an overview picture of the generation and transmission system and distribution system to the System Control Engineers The displays are dynamically updated and can be changed by duty engineers or triggered by pre-programmed conditions

The full graphic capability of the EMS and DMS systems is exploited to enhance user interface Zooming and panning of one-line diagrams are possible such that only relevant information is presented Colour schemes are devised to convey vital information such as voltage level or whether a circuit is dead or live (de-energised or energised) etc

Distribution Management System (DMS)

HK Electric is one of the few public utilities in the world to have implemented a gigantic scale of SCADA function in its distribution system where all distribution substations are installed with RTUs The DMS controls and monitors more than 3700 customer substations with over 130000 analogue 81000 digital as well as 18000 control points

Like the EMS the DMS is also equipped with SCADA Alarm Processing Tagging and Interlock Checking and HFD functions The DMSrsquo extensive telemetry and control capability enables System Control Engineers to locate and isolate faulty apparatus in the distribution network within a few minutes greatly reducing the time of electricity supply outage

The DMS also provides valuable data to other computerised systems Examples include bull Loading data are output to a Load Survey

System for distribution planning purposes and

bull Names of substations with supply interruption are passed to the Service Call System for efficient handling of customersrsquo service calls

Other advanced functions and applications provided by the DMS include Automatic Ventilation Fan Control Parallel Switching Study Distribution System Power Flow Short Circuit Calculation Outage Management System Switching Order Generation and Distribution Fault Identification Expert System
