Research On Application

The distribution grid communication network is an important part of electric power communication system. But it has became a limit of distribution network for the absence of effective communication method. This paper first introduces the characteristic and information requirement of smart distribution network, then makes a deep research and comparison on the communication technology such as PONWireless Network and PLC. Finally it presents a technology application scheme and system structure of distribution communication network.

Nowadays, voltage stability issues are the main problems around the world and therefore it is important that to maintain stable voltage stability. Series capacitor compensation plays an important role in the transmission line because it can improve the voltage stability as compared to shunt compensation. The Thyristor-Controlled Series Capacitor (TCSC) is selected in this project for providing capacitor compensation because its ability to control the amount of compensation in the transmission line, and operating in three different mode of region, which are resonance, capacitive, and inductive regions. The Fast Voltage Stability Index (FVSI) is used to determine the system’s stability and determine the weakest line in the system for TCSC placement. The TCSC sizing is optimized by using Differential Evolution (DE) optimization technique. All these processes are simulated on Institute of Electrical and Electronics Engineer (IEEE) 14-bus test system by using MATLAB. The proposed methodology was carried out in few tests, which are system contingency test, line outage test, power loss test, voltage profile improvement test and variable TCSC location. Based on the results, the overall voltage stability of the system was improved. The voltage magnitude for each bus had improved and the total power losses also reduced. Therefore, the optimization is successful and the study’s aim is achieved.

Research On Application

The evaluation of distribution network projects mainly rely on manual evaluation, with a heavy workload and high blindness that it cannot accurately reflect the effect of project, and yet cannot satisfy the needs of the development of the distribution network. With the automated development of distribution network, the total amount of data that can be acquired is constantly improve and perfect, which made it possible to apply computer aided software on the post evaluation. In this paper, it first introducing the comprehensive evaluation and analysis software into the post evaluation into distribution network projects, then put forwards the method of combining manual evaluation and computer aided software to reflect the effect of project construction, finally, analyses one project as a detailed example.
