Weight Allocation

Background: The Remote Terminal Units (RTUs) in the Distribution Automation System (DAS) are widely used in the field in recent years. It is lack of sample data in different operation status that makes the RTU maintenance improper. The weight allocation for the monitoring indicators in the health status evaluation needs to be identified efficiently and properly. Methods: A systematic health status assessment indicator system is constructed firstly. Then, a hybrid indicator weight allocation algorithm based on the Attribute Hierarchy Model (AHM) and grey relational degree (GRA) is proposed to identify the elementary item in the weight allocation under small sample condition. The final indicator weight would be dynamically adjusted according to the equilibrium coefficient, which is determined by the indicator condition parameter. Results: The simulation results show that the weight allocation can be effectively and reasonably adjusted according to the indicator value even under small sample condition. Conclusion: The expert experience and objective data laws are combined and used in our proposed dynamic weight allocation method. It can be used to assess the health status of RTU in the electrical power distribution network.

Power Failure in the power system is mainly due to the overloading. The possible damage to the area is losing a power. The Arduino Uno based load control system is a device which automatically control overload on generator by controlling power and cut-off supply whenever consumers exceeds the amount of power supplied for peak period. This is achieved by Arduino Uno, which detect overload and simultaneously cut-off the supply for the period of generator overloading. In this paper system can be automated into two stages are monitoring function and controlling function. In Monitoring function it has to record the meter reading at different location in the system, for normal as well as overload condition which is required for system planning. Distribution Supervisory control and Data Acquisition System (DSCADA) performs some of these monitoring function and controlling function about switching operation that is controlling of relay circuit breaker. The function Impacts on Consumer as well as reliability. The research work to be aimed at developing local full scale distribution automation system which can be control from secondary distribution substation to the consumer end. Power distribution automation expected for the broad areas. The project aimed at uninterrupted power supply for loyal energy consumer by implementation of this the problem of interruption off power supply due to energy misusing consumer can be avoided. This system provides the reliable operation at consumer end.
