Abstract

The placement of monitoring devices like micro-Phasor Measurement Unit (μPMU), which works 24 hours, at all nodes in the distribution system, is contributing to temperature rise. This temperature rise can be reduced by placing the μPMUs at selected nodes. Therefore, this paper depicted a hybrid approach for μPMUs optimal placement in the distribution system. Optimal placement recognises the placement set containing the least number of μPMUs with optimum redundancy with which the phasors of voltage, as well as the current, can be calculated at each bus of the system. Constraints such as communication link unavailability, zero injection buses, and network reconfiguration are considered in the optimal μPMU placement formulation. The proposed approach overcomes the downside of Integer Linear Programming (ILP) which provides a single optimal location set. The proposed approach automatically assigned μPMUs to buses connected to radial buses, established by the degree of each bus, and reduces the computational concern. Provided algorithm efficiency is checked out with IEEE 40 bus feeder and IEEE 85 bus feeder system under Matlab/Simulink environment.

基于混合方法的有源配电网络中微相位测量单元的布置

在配电系统的所有节点安装微型相位测量单元 (μPMU)（24 小时工作）等监测设备会导致温度升高。如果在选定的节点上安装微型相位测量单元 (μPMU)，就可以降低温升。因此，本文描述了一种在配电系统中优化放置 μPMU 的混合方法。最佳布点是指布点集包含最少数量的 μPMU 和最佳冗余度，通过这些冗余度可以计算出系统中每个母线的电压相位和电流相位。在最优 μPMU 布置公式中考虑了通信链路不可用、零注入母线和网络重构等约束条件。所提出的方法克服了整数线性规划（ILP）提供单一最优位置集的缺点。所提出的方法根据每条总线的度数，自动将 μPMU 分配到与径向总线相连的总线上，减少了计算量。在 Matlab/Simulink 环境下，利用 IEEE 40 总线馈线和 IEEE 85 总线馈线系统检验了所提供算法的效率。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
