"Parcellized-CIM" Standard and Its Application to SCADA/EMS Platform for Power Grid Systems WANG Lan / MAKINO Shigeyuki / MURAYAMA Hiroshi Accompanying the dissemination of smart grid technologies and the introduction of full liberalization of the electricity market, there is a growing need for technologies that facilitate the exchange of information among different electric energy systems. The Common Information Model (CIM), defined in the IEC (International Electrotechnical Commission) 61968/61970/62325 standards, is used to exchange data. However, there are some issues in the conventional CIM Unified Modeling Language (UML) model, such as the inability to manage the versions of each entity, nor difficulties to edit and manage the model and its instances in an integrated manner. To resolve these issues, Toshiba has proposed the IEC 62656-3 standard defining an interface between the UML and the tabular modeling methodology of IEC 62656, in which transformation rules between metamodels of the UML and IEC 62656 are specified. Accordingly, a CIM UML model can be represented in a set of structured spreadsheets called "Parcellized-CIM." Based on Parcellized-CIM, we have also developed the "parcimoser" framework for the design, construction, and maintenance of databases for power grid systems. The parcimoser has been incorporated into a transmission and distribution supervisory control and data acquisition/energy management system (SCADA/EMS) platform. Consequently, such SCADA/EMS platform with the parcimoser can seamlessly integrate applications developed by different vendors in a power system. Application of Production Simulation Technology to Medical Examination Services SUGIYAMA Naomi / NATOMI Tomo / TESHIMA Fumiaki Toshiba is making efforts to create new business value in the healthcare field by not only supplying products but also providing enhanced user experiences, with the aim of offering total solutions in a broad range of spheres including preventive medicine, prognosis/nursing care, and health promotion in addition to the various types of medical systems that it is already providing for diagnosis and treatment. In the field of preventive medicine, we have now applied a production simulation technology used for production design and work efficiency improvement to medical examination services such as comprehensive medical examinations and periodic health examinations, in order to reduce the waiting time of examinees in medical examination facilities. We have established examination route management methods to reduce the waiting time of examinees by leveling workloads in bottlenecked inspection areas, and confirmed the effectiveness of these methods through the results of simulation tests using actual data. Cooperative Load Carrying Technologies for Two Quadruped Walking Robots to Reduce Risk of Radiation Exposure during Decommissioning Work UEDA Koji / SUGANUMA Naotaka / NAKAMURA Norihito At the Fukushima Daiichi Nuclear Power Station, several operations in the decommissioning work are taking place in a high-level radiation environment. The need has therefore arisen for remote devices to perform various simple tasks including the carrying of equipment and construction materials on behalf of workers in order to reduce the risk of radiation exposure. Toshiba developed a quadruped walking robot to carry packed work tools, which has been applied to the reactor building investigations. In order to carry long and heavy loads such as pipes, we have now developed the following cooperative load carrying technologies using two quadruped walking robots: (1) a control technology to synchronize the timing of the start of walking of two robots, and (2) a control technology to maintain a constant distance between two moving robots while ensuring a sufficient margin for each robot. Experiments using two robots in which these technologies had been implemented confirmed that they could carry and unload a pipe of 2 m in length and 45 kg in weight on a floor with a level difference of 100 mm. Hydro Generators of Sogamoso Hydroelectric Power Plant, Colombia KINOSHITA Kentaro / ISHIZUKA Hiroaki / TOJO Hirotaka In Colombia, hydroelectric power generation accounts for a large proportion of overall power production due to the country's abundance of water resources. The Sogamoso Hydroelectric Power Plant of ISAGEN S.A. E.S.P., located north of Bogota, the capital, successfully started commercial operation in December 2014. The total output of the plant is 820 MW, which is equivalent to 8.3% of the total electricity demand in Colombia. The Toshiba Group supplied three hydro generators with the largest capacity in Colombia as well as electrical balance of plant (BOP) facilities during the approximately 5-year term of this project, in conjunction with its bases for the hydroelectric power generation business in Japan, China, North America, and Colombia. We have now supplied hydro generators providing about 45% of the total hydroelectric power generated in Colombia, and are contributing to the country's use of renewable energy through the ongoing development of hydroelectric power plants. µEMS for Smart Grid Demonstration Project on Penghu Island, Taiwan KHOR Mei Lian With the ongoing introduction of renewable energy systems in recent years, it has become necessary to improve the efficiency of electricity supply and demand on isolated islands that have to supply power independently and to construct smart grids in urban areas that already have developed social infrastructure systems including water supply, railway, and electric power networks. In Taiwan, the Industrial Technology Research Institute (ITRI) has been conducting the Smart Grid Demonstration Project on Penghu Island aimed at the construction of an energy management system (EMS) that will maintain the electricity supply and demand balance of the isolated island when the power grid is connected to the main island via a submarine cable in the future. Toshiba has supplied its µEMS (micro energy management system), developed as a primary platform for the monitoring and control of electricity supply and demand, to ITRI as part of the above project. The µEMS offers a voltage regulation function for the power distribution system, a function to control fluctuations in the output of photovoltaic (PV) power generation facilities, and a function to optimize the use of renewable energy systems connected to the existing power grid by controlling the energy storage system (ESS) and the inverters of PV power generation facilities through power generation prediction and planning applications for renewable energy systems. Data Anonymization Technique to Protect Privacy KOIKE Masanobu / Pakin OSOTKRAPHUN / ITOH Hidemasa With the ongoing introduction of business models that enhance the added value of products and services and create new value through the use of personal data, anonymization is expected to be a vital technology protecting personal privacy. Among data anonymization techniques, k-anonymization is the most promising because a record in a k-anonymized dataset is guaranteed not to be linked to an individual with a confidence level of more than 1/k. However, the knowledge obtained from a k-anonymized dataset is less precise than that in the original dataset due to information loss that occurs during the k-anonymization process. Toshiba has now developed a k-anonymization algorithm that reduces the amount of information loss by about 30% compared with existing techniques. This technique achieves effective utilization of personal data with higher accuracy while protecting personal privacy. |
