A general review of power quality standards and terminologies

In the next few years, more than 80% of AC power is to be processed through power converters owing to their benefits of energy conservation, flexibility, network interconnection, and weight and volume reduction in a number of equipment such as lighting arrestors, HVAC computers, fans, and so on.This paper gives an introduction on power quality (PQ), causes and effects of power quality problems. It also deals with power quality definitions, terminologies, standards, bench-marks, monitoring requirements, financial loss, and analytical quantification. It also discusses various types of nonlinear loads, which cause these power quality problems, they are illustrated, classified, modeled, quantified, and analyzed forassociated power quality issues.

SHARED NETWORKS: THE PATHS OF LATIN-CENTRIC INDIGENOUS NETWORKS TO A PLURIVERSAL INTERNET

This research paper examines the emergence of shared networks in Tseltal and Zapoteco communities in Chiapas and Oaxaca (Mexico): internet first mile signal-sharing practices that articulate interconnection infrastructure and coexistence values to extend the internet to areas where the services of existing larger internet service providers are unsatisfactory or unavailable. In the case studies analyzed, indigenous people become internet codesigners by infrastructuring for their own local networks and interconnecting to the global internet. The paper argues that a hybrid materializes at the level of network interconnection when comunalidad, or the way of these communities, supported by unlicensed frequencies of the electromagnetic spectrum, towers, radio antennas, houses rooftops, routers, and cables meet the values of the internet service providers and their policies. Shared networks are a result of what these arrangements both enact and constrain, and the evidence of vivid struggles of Latin-centric indigenous networks towards a pluriversal internet.

Federal Synergy Computing Model Based on Network Interconnection

To solve the shortage problem of the computing power provided by the single machine or the small cluster system in scientific research, we offer a collaborative computing system for users. This system has massive operation ability. It introduced a scalable mixed collaborative computing model. Through the internet and the heterogeneous computing equipment, the system uses the task decomposition model. This system can solve the research and development problem because of the shortage of capacity. To test the model, a subtask decomposition example is used. The results of the example analysis show that the computing work can obtain the shortest computation time when the number of calculation nodes is more than the number of subtasks; Maximum calculation efficiency can be achieved when the number of the calculating nodes closes to the number of subtasks. Through joint collaborative computing, the extensible mixed collaborative computing mode can effectively solve the mass computing problem for the system with heterogeneous hardware and software. This paper provides the reference for the system, which provides large scale computing power through the Internet and the research problem of due to the lack of computing ability.
