Standards, power distribution, monitoring and control of electrical heat tracing, a global view

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.

PurposeResulting from large government interventions, India could attain 99% electrification in March 2019. However, the consequences are revenue losses due to lack of real-time efforts in bringing operational efficiencies of the power distribution companies (discoms). Distribution franchisees operate as agents to the discoms for performing their contracted functions in smaller high-loss making areas under jurisdiction of a discom. This study aims to explore how rural franchisees help or hinder requisite results.Design/methodology/approachA qualitative embedded multiple-case study was conducted. The case focused on two franchisees engaged in metering, billing and collection functions of a high-loss-making rural area dominated Indian state-owned discom. Data were collected through documents, personal observations and semi-structured in-depth interviews with franchisee employees situated at different levels of the organizational hierarchy. A review of pertinent literature and government documents was utilized in forming the codes for collecting the data.FindingsIt could be argued that franchisees with strong financial capability, human resources support and monitoring and control facilities could contribute effectively in generating revenue from rural and interior electrified mass. The analysis revealed various challenges serving as hindrances in achievement of contracted targeted outcomes. The analysis resulted in highlighting factors that if implemented could result in the needed outcome.Practical implicationsThis study could be generalized only to similar socio-economic conditions. The findings could provide policy makers with valuable insights to emphasize on creating win–win situations for all the stakeholders to encourage franchisee participation.Originality/valueThis study is unique, as there is a dearth of empirical evidences relating to operational efficacies of these franchisees.

Improving reliability of a power network is an issue of great importance for power distribution companies. The aim stated by the President of Energy Regulatory Office to improve the reliability of the distribution network includes steps towards improving the monitoring and control of the network managed by distribution companies. Ensuring continuity of energy supply is one of distribution companies’ duties and one of the criteria used to assess the effectiveness of network operation. Distribution companies all over the world employ indices SAIDI, SAIFI and MAIFI to determine mean values concerning the number of time of interruptions per consumer in a year. The paper deals with methods of correct and precise determination of the values of the reliability indices SAIDI, SAIFI and MAIFI by means of the application Advanced Metering Infrastructure in the distribution network.
