Tiivistelmä
Due to the natural monopoly nature of the electricity distribution business, the operation of the Distribution System Operators is regulated by the authority. The Electricity Market Act appoints the Energy Authority to be responsible for the regulative measures. A new regulation period took place in the beginning of year 2016. The regulation model guides the operation of the Distribution System Operators, and for example the annual realized KAH values have direct economical impact on the DSOs via the allowed profit. Due to the occurred major disturbances during recent years, the requirements for the IT systems are increasing. The large amount of outages and increasing amount of reporting requirements increase also the role of automatization in the outage reporting.
One of the objectives of the thesis was to describe the IT systems used by a few Distribution System Operators and the information flows between the systems from the aspect of outage reporting. In order to find out what are the main reasons behind the particular IT system integration choices, representatives of five Distribution System Operators were interviewed. Information of the IT systems and the information flows between the systems were gathered, and the processes regarding the outage management and outage reporting were clarified. The objective was also to find out the used protocols, sources of the information and the communication types of the information flows related to the outage reporting. What information is required and what is the demand for the information are described as well. The operational objective of the thesis was to create a new outage report according to the needs.
As an outcome of the thesis the chosen Distribution System Operators’ IT systems and information flows between the systems related to the outage reporting are described. For the reporting functions of ABB MicroSCADA Pro DMS600 product, development ideas were gathered from the Distribution System Operators and development requirements from the Energy Authority’s documents and the Finnish Energy’s outage statistics instructions. As a result requirements for new outage reports were discovered. The new outage reports are required as compulsory by the Energy Authority. During the thesis three outage reports were developed to represent the changed reporting requirements, and two entirely new reports were implemented with SQL language according to the new requirements. The implemented reports respond to the requirements regarding the distribution reliability requirement classes and the key figures of LV network outages defined by the Energy Authority.
