In order to enhance the support capacity of integrated control of large power grid, unified consumption of clean energy and coordinated interaction of source-grid-load, the State Grid proposed the construction of next generation of grid dispatching system. The core feature of the next generation system is “physical distribution and logical unity”, and the user oriented man-machine subsystem is an important link. This paper analyzes the function and performance requirements of the next generation of human machine subsystem, and proposes a lightweight human-computer cloud terminal interaction architecture oriented to micro-service based on the idea of separating the front and rear ends of the Internet. The software architecture of the system and the hardware network architecture supporting horizontal expansion are elaborated in depth. The design architecture can effectively reduce the requirements for terminal hardware, and can adapt to the different terminals such as tablet computer and mobile phones, and can meet the requirements of the next generation system for human-computer “location independent, simultaneous display, and authority constraint”.

In view of the present situation that the human-computer interface of the Power Market Operation System is mainly dependent on the software customization development, a configuration graphics system is proposed and implemented to meet the needs of multi-time, multi-dimension and flexible display of trading business. In this paper, a hierarchical structure of transaction configuration graph based on SOA design is proposed, the role of each layer in the architecture and its implementation are also discussed. A definition and implementation method of configuration primitive based on an event-property-binding mechanism is described in detail. It can freely switch over a variety of transaction related dimensions including "time" through the screen interaction. The transaction configuration graphics software provides the ability of transaction graphics system to quickly generate business graph-interface. It reduces the difficulty of system development and maintenance, and it enhances the flexibility of graphics to display multidimensional transaction data.

The circular agriculture is conducive to achieving the purpose of efficient agricultural economy and environment-friendliness. Based on the perspective of circular agriculture theory, this paper builds the evaluation indicator system for circular agriculture, and uses entropy method and Matlab analysis tool to carry out the comprehensive evaluation of the level of agricultural development in Chongqing City during the period 2003-2012. It analyzes the obstacles to the development of circular agricultural economy in Chongqing City in 2012, and finally puts forward the corresponding recommendations.

The development of smart grid has proposed higher request to the intelligent dispatching in power construction. To meet these requirements, in the basis of the full research on dispatchers' actual habits, this paper proposed the use of the existing power grid analysis theory to establish power grid running status indicators and the novel hierarchical display frame design, which combines with visualization technologies. Based on this, it has built the interactive visual platform of real-time power grid status cognition, which shown the six grid cognitive information excellently and visualized early warning of internal risk equipment and external meteorological risk. It has greatly improved dispatchers' emergency treatment level and promoted the development of intelligent dispatching.

Aiming at the situation in Grid EMS visualization software about the ubiquitous defects of pool interaction, inflexibility and difficult to reuse, the paper designs and implements an architecture of Theme-Scene-based extendible interactive visualization platform in energy management system. This paper presents the method of how to define and construct a grid application theme scene and displays the visual effects about application business from different viewpoint, therefore realizing the interaction between grid application and visualization. The interactive visualization extendible platform is convenient to flexibly extend application business on visualization need, and greatly improves and enhances the traditional visualization display effects.

With the smart grid construction proceeding further, requirements increase on model and information sharing between control center and substation, and the current commonly used communication protocol between control center and substation has been unable to meet the demand of communication. This paper proposes a real-time service communication protocol, which is based on IEC61850, directly mapped the abstract communication service interface (ACSI) to the TCP/IP communication protocol stack, to build up a communication protocol in smart grid construction needs, meet the intelligent seamless communication requirements between control center and substation. Also the conversion model method and calibration method is also proposed.

Scientific visualization is a multidisciplinary technology, which integrates computer graphics, data mining, human-machine interface theory, and combines with the applied sciences, and provides an intuitive way to show valuable data in engineering area, and provides means to operator for exploring and studying physical phenomena. In recent year visualization techniques are used more widely in power system, more and more showing means is provided, and visual effects is also getting better, but these can't meet high demand of dispatcher in power system. How to make visualization technology more practical is a difficult problem needed to be urgently solved. This paper proposes several methods for practical research in visualization. Based on application already deployed in power system, we analysis the way how to improve practicality of scientific visualization in the power system, and introduce how to use visualization techniques for advanced application in power system. The practical research in this paper is helpful to raise the level of dispatching in power grid and provides strong technical support for changes from traditional dispatching to intelligent dispatching.
