Revitalization of Remote Control Centre at Elektro Primorska Outage Management System (OMS)

Transcription

1 Revitalization of Remote Control Centre at Elektro Primorska Outage Management System (OMS) Alen Varži M.E.E. Head of Department Control Centers Smart Grid Meeting November, 9-10, 2011.

2 KONCAR Group Founded in 1921, consists of 20 dependent companies and 1 affiliated company, has 4000 employees. Business areas: Energy generation, distribution and transmission Electric traction Industry Information and Communication Technologies ICT Household apliances Annual sales amount to 350 million euros, more than half is exports. During recent years KONCAR group has delivered products and plants to more than 100 countries on all the continents.

3 Kon ar Power Plant and Electric Traction Engineering Inc. Part of KONCAR Group, 100% ownership of KONCAR Electrical Industry Inc. In charge of engineering activities for complex plants and facilities in power generation, transmission and distribution, transport and industry. Implementation of complex turn key projects. Over 260 employees (75% with University degree) Annual income - cca. 85 million euros (25% of KONCAR Group) Export cca. 45 %

4 Project of revitalization of RCC at Elektro Primorska Long term cooperation between Kon ar and EP was successfully continued on Project of revitalization of RCC Elektro Primorska is one of electricity distribution operators in Slovenia, with more then customers on cca km 2 Project initially divided in two phases: 1. Replacement of old Kon ar s SCADA system based on PDP computers, with Network Manager system (ended in June 2007) Implementation was carried out without any breakup in functionality of DC using Kon ar s Front End Processor Additionally developed Proza Open application for reporting 2. Outage Management System (OMS)

6 OMS implementation key points Deregulation in the Electric Utility industry is forcing the utilities to be more concerned with the issues of their customers Distribution companies are becoming more service quality oriented, and outage management is one way to lower costs and improve customer service According to some studies OMS reduces time in locating outage by 30%, while reducing personnel and equipment costs by 25 % Prior to the OMS implementation, Elektro Primorska recorded outages manually, so they sought an automated system with the ability to track outages in real time, to rollup outages to a probable outage device, and to improve overall reporting.

7 OMS implementation The implementation of an OMS can be complex, as it is often integrated with several other systems and requires good quality data in order to operate correctly. Customer Information System - provides the OMS system with customer data that is required to link the customers to the network and to identify customers when they call in (at EP used for entering new customers, invoicing, tariffs, etc.) DE interface provides OMS system with network information about devices and their connectivity. This interface is important for network planning, with data UP TO DATE AND ACCURATE. SCADA interface provides the OMS system with MV and LV outage information and switching information

8 OMS implementation NETWORK MODEL CUSTOMER DATA SCADA SYSTEM OMS WORK MANAGMENT

9 Data requirements Customer Data Unique customer identifier (e.g. meter, customer or account number) Customer name Customer address Contact details Customer type (used for prioritization and reporting)

10 Data requirements Network Model Data In order for the OMS to infer relationships between faults, it needs to analyze an electrical network model. Unique device identifier/name (external id) Device type Connectivity (from device, to device - nodes)

11 Outage Managment System Trouble Call Management Outage Analysis Crew Management Outage Information Outage Reporting

12 Trouble Call Management Trouble Call Management (TCM) manages incoming trouble calls, and outage information so operators can provide customers with current, up-to-date information Calls from customers and non-customers are registered in OMS system Operators use the TCM web displays to enter the calls information through predefined forms

13 Trouble Call entry form

14 Outage Analysis The Outage Engine analyzes trouble reports and network connectivity changes to create and maintain an up-to-date list of out-of-service loads OMS system periodically groups the calls into inferred outages and presents outages in the form of alarms and graphical symbols The inference from calls to outages is done automatically by analyzing the pattern of the calls along the network connectivity model

15 Crew Management Crew Management tracks field crews and their associated work including crew types, assigned personnel, vehicle types, equipment and task times Operators use OMS system to prioritize outages, choose crews for outages, and track assignments and work status of crews OMS system provides a list of available crews within a specified geographic radius with their backlog and status, and informs the operator of any crews that are already assigned to the same circuit

16 Outage Information Outage Information supports viewing of outage details using land base map displays and tabular lists, through web technology The system provides a global view of the situation with the drill-down capabilities to bring the detailed information into view Enables users to track power outages from the time problems are reported until power is fully restored It stores information about trouble calls, customers, employees, equipment, and circuit data in a database and makes it available to restoration teams

17 Outage information

18 Outage Reporting Data stored can easily be used for reports and statistical purposes OMS system summarizes outage status and other information (e.g., the number of calls, the number of affected customers, the number of restored customers, and the number of customers still out of service, etc.) for both periodic and on-line situation reports to the utility management Reliability indices such as SAIFI, SAIDI, CAIFI, and CAIDI can be calculated by area, substation or feeder

19 Benefits Financial benefits quicker and more accurate location of outages in network by predicting outage location and indicating possible breaks improved response time reduced time of outage restoration quick access to priority customers, calls received and customers affected by an outage improved network reliability reduced personnel needed to manage an outage

20 Benefits Organizational benefits fulfilling legal obligations towards supervisory entities regarding reporting more simplified monitoring of network activities and their analysis system operators have access to a user-friendly interface and intuitive menus to quickly and efficiently dispatch crews based on geographical and tabular data. marketing and customer service representatives can access the system to gain updated outage information and accurately relay it to the public, without having to interrupt the system operators.
