The SIRIUS supervisory system for the Kyushu Shinkansen manages traffic, rolling stock, and other aspects of line operation. The system was commissioned in March 2004 to coincide with the commencement of operations on part of the Kagoshima route of the Kyushu Shinkansen (between Shin-Yatsushiro and Kagoshima-Chuo Stations). The system was subsequently upgraded in November 2010 in readiness for the commencement of operations along the entire line (between Hakata and Kagoshima-Chuo Stations) in March 2011. To support through-trains running on both the Sanyo and Kyushu Shinkansen railway lines, the system includes interconnections with the COMTRAC traffic management system for the Tokaido and Sanyo Shinkansens. To provide the high level of reliability demanded by a Shinkansen system, the automatic route control equipment at the heart of the system features the new CF-1000/FT fault-tolerant model with synchronization control of four-fold CPU redundancy at the OS level.

Railways are a key form of public transportation, yet the electric power shortages resulting from factors such as the impact of the Great East Japan Earthquake on nuclear power plants have made it more necessary than ever that they seek to save electricity. Another issue is the action being taken around the world to deal with the problem of global warming. Hitachi has developed a system for the storage of regenerative power that uses the same lithium-ion batteries as hybrid cars to store and reuse this energy in trains. The system was commercialized in 2007. In some cases, the installation of this system produced savings of more than 10% in power consumption. Hitachi intends to accelerate the deployment of this system to reduce railway power consumption in Japan and other markets.

OVERVIEW: A renewable energy feed-in tariff took effect in Japan in July 2012, and is expected to accelerate the adoption of photovoltaic power generation and other forms of renewable energy. Due to restrictions in the building of photovoltaic and wind power plants, there are expected to be increasing numbers of cases where such plants are built in remote locations far from the places where large amounts of energy are consumed, both in Japan and internationally. For this reason, problems related to the stabilization of power grids between energy production and consumption locations may grow serious. To deal with this situation, Hitachi is working towards the realization of power supply stabilization and wide-area interconnection by pursuing efforts in power system stabilizers, SVCs, energy storage systems, high voltage DC transmission systems, and other power grid technologies.

After aplant is constructed, the plant owners need to manage not only production, but also the maintenance of equipment that requires specialist knowledge and experience. The obstacles to achieving this include a shortage of maintenance technicians, rising maintenance costs due to the aging of industrial equipment, and the difficultly of training maintenance staff Hitachi is drawing on its plant construction activities to strengthen its plant maintenance management business and work together with its customers over all operations,from plant construction to after-sales service. Key factors in achieving this are the use of ICT and the service infrastructure that supports plant maintenance. © Hitachi, Ltd. 1994, 2013.

The market for video surveillance systems has been growing, with the technology being seen as essential for preventing unauthorized or criminal activity at logistics or financial services branches, and for quickly resolving violent incidents and similar. With the spread of networks in recent years, there has been growing demand for use of these systems in business. This demand extends beyond existing applications for preventing crime to also include uses such as remote monitoring to keep track of people and equipment, and image analysis to support customer operations and business management. Hitachi has been developing cloud-based video surveillance systems to meet this demand, and has plans to extend this development to future cloud services such as using image analysis for customer business support and equipment operation monitoring. © Hitachi, Ltd. 1994, 2014.

An increasing number of companies are seeking to operate multiple production sites, and many are choosing sites in the A SEA N and other nations of the Asian Belt Zone. However this poses numerous challenges, including the collection of local information and differences in culture, business practices, laws, and legal systems. In particular many companies considering the construction of new plants are looking to resolve problems in a variety offields, especially those that relate to know-how and conformance with local requirements. Based on its extensive past experience, Hitachi is able to supply integrated solutions for industiy that extend from plant construction through to things like air conditioning, utilities, and waste water treatment, and that take account of local customs and the relevant planning and legal systems. © Hitachi, Ltd. 1994, 2013.

Having set a target of replacing 40% of its electric power generation capacity with renewable energy by 2030, the state of Hawaii in the USA is proceeding with the installation of wind and PV power generation. To aid this work, a smart grid demonstration project is being conducted on the Hawaiian island of Maui under the leadership of NEDO. The aim of the project is to solve the problem of how to use EVs to stabilize the supply of electric power despite the fluctuating output of renewable energy. Hitachi commenced operation of the EV Energy Control Center for controlling EV charging in December 2013. It is now working on the development of VPPs, with advanced technology for using EVs as a distributed generation system. © Hitachi, Ltd. 1994, 2014. All rights reserved.

OVERVIEW: The scope of application of international standards has been growing as people seek ways of resolving global issues. There has also been a trend in recent times toward the introduction of standards for services. These service standards are intended to apply not to individual technologies but to actual services in a particular field. There is also a strengthening move toward international standardization of social infrastructure systems, a field that in the past did not need to take account of international standards. Hitachi is actively involved in international standardization. In the field of smart cities, Japan proposed the establishment of an ISO committee for standardizing indicators used to evaluate the performance of community infrastructure, resulting in the creation of the new ISO/TC 268/SC1 subcommittee. As a member of the Japanese team, Hitachi assisted with the proposal to establish this committee and with the writing of standards.
