Study on Key Technologies of Power Dispatching Control System under the Background of Cloud Computing

In order to adapt to the development and application of power dispatch control systems in the future cloud computing environment, this study proposes to make full use of the elastic characteristics of cloud computing to construct a new power dispatch control system architecture. First, we analyze the shortcomings of the traditional power dispatch control system architecture, from the perspective of architecture complexity, operation and maintenance, universality and disaster tolerance. Secondly, combining the characteristics of the existing dispatch control system, we propose a new power dispatch control system architecture that conforms to the cloud computing platform. Finally, we emphatically analyzed the key technologies for key breakthroughs needed to realize the power dispatching control system architecture. Through the comparison of traditional and new power dispatch control system architectures, it can be considered that the new power dispatching control system architecture has greatly improved reliability, flexibility, safety and economy, and has certain advantages.

Centralized Control System of the Flotation Department: Ross-Eshby Principle

The aim of the study is to scientifically substantiate the need to use the axiomatic approach when choosing and studying the processes of centralized dispatching control of technological parameters for a complex of flotation machines. During the research, the au-thors performed: comparison of a real object and its properties with the classical control axioms of system analysis; substantiated the use of a hierarchical structure of interrelated technological parameters and their application for situational management. Methods of classical control axioms of system analysis were used for the research. The authors formu-lated the criteria for situational management, the concept of visualization in the dispatching system. The results obtained allow us to assert that the implementation of the Ross-Ashby principle significantly increases the controllability of technological processes with a large number of units and measured parameters.

Research and application of graphic software architecture for power grid dispatching control system

Currently, the independent design and development of power grid automation system cannot meet the urgent requirements of integrated system for electric dispatching, monitoring and synthetic analysis and decision-masking. In accordance with this situation, a general power grid dispatching control graphics software architecture based on the modular hierarchical theory is proposed. The architecture extracts and abstracts the common modules of different system graphics software architectures to build an integrated basic development platform. Based on this platform, an integrated graphical interactive software for power grid dispatching, power distribution network or substation supervision can be quickly developed. In this paper, the overall architecture, modular hierarchical theory, graphics general API and the key technologies for this architecture are described in detail. This architecture has been applied to the development of multiple power grid control graphics software, and the engineering application is performing well in reality. In a word, the architecture proposed in this paper satisfies the needs of power grid control integration, and effectively reducing system

On the organization of excavation and transportation equipment in the coal-bearing zones at open pit mines

One of the essential issues of the benches’ development procedure is the choice of the method of seam development in the complex structure: joint development of rock and coal seams in one complex face or their separate excavation in blocks of 50-100 m in length. The decision of this question is connected with the mode of mining works, represented by the schedule of stripping and winning works. The choice of one or another method is connected with operative-dispatching control of haul trucks delivery. When rock and coal are mined together in a complex face, overburden haul trucks should be supplied for loading rock and coal haul trucks for coal in turns. It is organizationally difficult to supply haul trucks of different purposes during the shift. It is necessary to proceed from the shift (daily) planning of haul trucks supply for specific faces. In addition, it is necessary to take into account that rock and coal faces are often located on opposite sides of the quarry pit. This article studies the issue of organizing the operation of excavation and loading equipment during the mining of the coal-bearing zone of the open pit in order to reduce the loss of output of haul trucks.
