Loss reduction strategy and evaluation system based on reasonable line loss interval of transformer area

As the wiring of distribution network becomes more and more complex, it is difficult to calculate the theoretical line loss of low-voltage distribution transformer area and the evaluation index of transformer line loss is extensive. In this paper, a reasonable interval calculation model of line loss is established based on the data of electricity information acquisition system. Firstly, the collected data are processed in the image format, and then the line loss calculation model is established based on the convolutional neural network. This model can estimate the reasonable line loss interval according to the operation data of different transformers. On this basis, the line loss evaluation system is established and the loss reduction strategy of abnormal transformer is formed. The method in this paper can be used to evaluate the line loss level of distribution transformer area more accurately. It also can improve the quality and efficiency of line loss lean management and produce certain effect for electric energy conservation and improving economic benefit of power supply.

Fault location of distribution networks based on multi-source information

In order to promote the development of the Internet of Things (loT), there has been an increase in the coverage of the customer electric information acquisition system (CEIAS). The traditional fault location method for the distribution network only considers the information reported by the Feeder Terminal Unit (FTU) and the fault tolerance rate is low when the information is omitted or misreported. Therefore, this study considers the influence of the distributed generations (DGs) for the distribution network. This takes the CEIAS as a redundant information source and solves the model by applying a binary particle swarm optimization algorithm (BPSO). The improved Dempster/S-hafer evidence theory (D-S evidence theory) is used for evidence fusion to achieve the fault section location for the distribution network. An example is provided to verify that the proposed method can achieve single or multiple fault locations with a higher fault tolerance.

An Efficient Task Scheduling Method for the Unified Interface Platform of the Electric Information Acquisition System

Due to the large and frequent static data interaction between the Electric Information Acquisition System and the external business systems, researching on using limited server sources to do an efficient task scheduling is becoming one of the key technologies of the unified interface platform. The information interaction structure of the unified interface platform is introduced. Task scheduling has been decomposed into two stages, task decomposition and task combination, based on the features (various types and dispersed) of large static data. The principle of the minimum variance of the subtasks data quantity is used to do the target task resolving in the decomposition stage. The thought of the Greedy Algorithm is used in the taskcombination. Breaking the target task with large static data into serval composed tasks with roughly same data quantity is effectively realized. Meanwhile, to avoid the situation of the GA falling into the local optimal solution, an improved combination method has been put forward. Moreover, the new method creates more average composed tasks and making the task scheduling more effective. Ultimately, the effectiveness of the proposed method is verified by the experimental data.

Comprehensive Performance Evaluation Strategy for Communication Networks Selection in Smart Grid

Abstract Different communication networks are used in the different application environment of the smart grid. So, how to effectively select the communication networks with the optimal comprehensive performance is an important issue for the power management corporations. A novel comprehensive performance evaluation based on Exponential Scale Analytic Hierarchy Process (ESAHP) and Grey Analytic Hierarchy Process (GAHP) for the communication networks selection is proposed in the electricity information acquisition system. The ESAHP is used to calculate the weight of each communication performance index and the economic performance index, and the GAHP is adopted to evaluate the economic cost of the different communication modes. The optimal comprehensive communication model can be selected by comprehensively comparing the communication performance and the economic cost. The test results show that the assessment model can effectively evaluate the comprehensive performance of the different communication networks selection in the electricity information acquisition system of the smart grid.
