LATEST TRENDS IN GEOSPATIAL TECHNOLOGY FOR ELECTRICITY SECTOR A Path breaking Technology for Network Maintenance and Optimization Yousef Al-Jaidah Manager, Electricity Network Planning KAHRAMAA www.km.com.qa Introduction – KAHRAMAA Electricity Network Affairs Electricity Network Planning Electricity Sector, Some Challenges Raising to the Challenges The Solution GIS System Evolution An Integrated Approach Delivery Channels KAHRAMAA is the sole distributer of Electricity and Water in the State of Qatar. • In the Electricity sector KAHRAMAA operates with 230 Primary High Voltage Substations connected by a total of 1,880 km of Primary Overhead Transmission Lines and 2,530 km of underground HV cable network. The network is coupled with 12,150 Medium voltage substations (11 kV) and more than 11,600 kilometres of underground and overhead cable lines. • KAHRAMAA maintains a water infrastructure consisting of 6789 Km of Water pipeline networks with 28 Storage Reservoirs having total capacity of 641.5 Million Gallons. Mission Objectives To provide Safe, Secure, Reliable & Adequate electricity supply to all type of customers in the state of Qatar, in conformance to international and regional standards and in a timely manner with the least possible cost. 1. Customer Satisfaction • Understand and meet customers’ needs and expectations 2. Supply Efficiency • High Quality Power supply • Dispatch IPP through a secure and reliable network 3. Quality • Meet the overall Electricity quality needs through least number of Power Interruptions & Eliminate Outages • Committed to Plan and Design Qatar’s Electrical Network development using efficient technologies, data and materials and strive to satisfy our customers. • Coordinate with other utility agencies to have a harmonious expansion of State’s assets and infrastructure. • Review and update Material Specifications. Ascertain the international standard materials are used in KM’s Network. How to Improve Power System Reliability Maintain Power Quality Optimally Utilize the Power Delivery Assets Reduce the equipment failures Reduce the planned / unplanned outages in the system Increase the awareness for energy Conservation - Tarsheed Integrate Diesel Generator based micro grids into main network Fishbone Diagram is helpful in identifying potential factors causing an overall effect Equipment Failure Reduces System Reliability Reduces Power Quality Over utilization of Assets Increase in Equipment Failures Decrease in Power Quality Under utilization of Assets Increases Network Cost Un utilized Installed Capacity Outages Reduces System Reliability Reduction in utility income Bigger challenges provide bigger opportunities Meeting these challenges gives raise to better rewards Rewards are in terms to Reliability, Quality, efficiency and economic benefits to consumers and to the utility Qatar’s Electrical Network has Primary Substations Secondary Substations Consumers – 230 – 12,159 – 295,000 and increasing A GIS System that can handle Comprehensive and accurate inventory of Electrical Assets Interconnectivity between the assets with Under ground and Overhead lines A Comprehensive Service Information that is integrated to the GIS System and that can be retrieved from within the GIS software Traceable network from the Electrical feeder to the connected customers along with all the electrical assets in between A system that can be integrated with any database with ease. An Electrical aware GIS system can GIS Databases Electricity Network Cables OHL Transformer Switch Bus Bar Circuit Breaker Land Base Topography Parcels Make it easy to locate the Electrical Assets Help create a comprehensive maintenance schedule for a given area / zone Identify the customers effected for switching programs Effectively managing high priority areas while preventive maintenance scheduling Identifying the electrical feeders in an outage Integrating customer messaging system for any electrical activity KAHRAMAA has awarded a contract to implement an Enterprise GIS solution using ArcFM technology ArcFM™ is a powerful extension of ESRI's ArcGIS® platform that provides a complete, enterprise utility solution specially for energy sector. The ArcFM Solution allows utility businesses to make use of a single integrated environment to manage and map multiple assets, leveraging all the power of ArcGIS’s object-oriented system.
