In most of Chinas rural areas, the devices of power distribution area are low configured, simply designed and installed, and have few functions but lots of forms. Beyond, most of them only implement simple functions of power distribution and metering. They couldnt meet the needs of transformation of rural power grid. So its extremely urgent to reconstruct and build intelligent rural power distribution and realize the standardization of information model and the intelligent integrated management of power distribution area to improve the quality and reliability of power supply. In this paper, we analyzed the current development situation of Chinas rural area. Then from the aspect of solving the lagging intelligent level of rural power system, we do some research about developing a new intelligent integrated distribution box and distribution transformer terminal , then we propose the intelligent manage system of power distribution area to realize high intelligent level of power distribution management, high level monitoring and control and greatly improved manage efficiency. At the same time, we enhanced the serving strength for the customer and help to improved the entire intelligent power load , so we could supply high quality power to our customers.

The steady decline in the prices of distributed energy resources (DERs), such as distributed renewable generation and storage systems, together with more sophisticated monitoring and control strategies allow power distribution companies to enhance the performance of the distribution network, for instance improving voltage control, congestion management, or reliability. The latter will be the subject of this paper. This paper addresses the improvement of continuity of supply in radial distribution grids in rural areas, where traditional reinforcements cannot be carried out because they are located in secluded areas or in naturally protected zones, where the permits to build new lines are difficult to obtain. When a contingency occurs in such a feeder, protection systems isolate it, and all downstream users suffer an interruption until the service is restored. This paper proposes a novel methodology to determine the optimal location and size of micro-grid systems (MGs) used to reduce non-served energy, considering reliability and investment costs. The proposed model additionally determines the most suitable combination of DER technologies. The resulting set of MGs would be used to supply consumers located in the isolated area while the upstream fault is being repaired. The proposed methodology is validated through its application to a case study of an actual rural feeder which suffers from reliability issues due to the difficulties in obtaining the necessary permissions to undertake conventional grid reinforcements.

Modern power grid is an important part of national energy strategy. Smart grid is one of the directions to modernize the electricity grid. Smart grid is the intelligent of power system, It is also known as the grid 2.0.It is based on integrated, high-speed bidirectional communication network ,It use the advanced sensor and measuring technology, use advanced equipment and control method to realize the application of the power grid reliability, safety, economic, efficient, environmental friendly and safety. High speed, bidirectional, real-time, and integrated communication system is the foundation and key point when monitoring and control smart grid. So How to improve the communication technology is very important.

Introduction. The Control System of Maglev Vehicles (further - CSMV) has key value for development maglev. Purpose. In article management by safe movement of maglev vehicles with use of digital radio channel are considered, the international experience is analysed and conclusions for Russian practice are drawn. Methodology. The following methods were used: system approach, analysis and synthesis, generalization. Results. CSMV should consider physical possibilities of magnetic levitation, factors and the restrictions influencing these possibilities, including - the factors connected with safety. CSMV should possess complex of functions allowing effectively, full and safely to realise possibility of magnetic levitation in conditions of specified factors and restrictions. Practical importance. The basic practical results, which can be received by working out CSMV, are: - creation CSMV with high level of control automation and consequently effective and safe; - working out within CSMV typical design decisions, applicable for adaptation to monitoring and control of problems various systems and maglev vehicles; - creation of preconditions of design and perfection of all complex of regulatory framework, conformity which provides safety of maglev infrastructure and vehicles; - reception of interaction experience of the Customer, the research and design organisations, the industry enterprises, the assembly and maintaining organisations at stages of life cycle of CSMV, as key subsystem of maglev. Conclusion. The main appointment of CSMV - creation and constant provide of conditions for safe and effective functioning and development of this new type of transport.

In this chapter, we present the justification and a feasibility study of applying the Byzantine fault tolerance (BFT) technology to electric power grid health monitoring. We propose a set of BFT mechanisms needed to handle the PMU data reporting and control commands issuing to the IEDs. We report an empirical study to assess the feasibility of using the BFT technology for reliable and secure electric power grid health monitoring and control. We show that under the LAN environment, the overhead and jitter introduced by the BFT mechanisms are negligible, and consequently, Byzantine fault tolerance could readily be used to improve the security and reliability of electric power grid monitoring and control while meeting the stringent real-time communication requirement for SCADA operations.
