Design And Implementation

With the development of national economy, the demand for electricity from all walks of life has been gradually increased. People also put forward higher requests to the reliability of power supply. Feeder automation can quickly cut off the faulty line to ensure the safe and stable operation of the line. Under the sustainable development of modern society, people attach a great importance to all aspects of smart power grid construction, which is also significant for the smart grid distribution work. To ensure the reliable and high-quality power supply environment, the scientific and reasonable design and planning of power distribution automation system shall pay attention to arranging power distribution, and the appropriate feeder automation operation mode shall be selected. Only in this way can we ensure that the power outage is short once a fault happening in power grid system. At the same time, the line loss rate can be reduced, the efficiency of power supply can be raised, and issues in power equipment investment can be effectively treated. This paper mainly discusses the design and implementation of feeder automation, puts forward some practical application measures, and provides reference for the stable operation of feeder automation.

Output Characteristics

With the development of smart power distribution technology in the future, a large range of power supply load (such as distributed wind power generation) will appear on the power receiving end. When distributed wind power is connected to the power grid on a large scale, it will have a certain impact on the safe and stable operation of the power grid. However, if the wind power output characteristics can be analyzed and the wind power output is properly regulated, the one-way flow of power from the distribution network to the user side will be broken, so that the future "network-load" has dual interaction characteristics based on response and substantial power exchange.

Distributed Power

In distribution networks with distributed power supplies, distributed power supplies can also be used as backup power sources to support the grid. If a distribution network contains multiple distributed power sources, the distribution network becomes a complex power grid with multiple power supplies. When a short-circuit fault occurs at a certain point on the power distribution network, the size, direction and duration of the short-circuit current are no longer single due to the existence of distributed power, and will vary with the location and capacity of the distributed power supply system. The change, in turn, affects the current in the grid, resulting in the generation and propagation of additional current. This power grid of power electronics will cause problems such as excessive standard mis-operation, abnormal heating of the converter and component burnout, and communication system failure. It is of great and practical significance to study the influence of distributed power in distributed power distribution networks.

Service Restoration

Whena fault of the distribution network has occurred, it is necessary to pinpointthe type of the fault and its location and to isolation the fault by sectionswitches. It is then the task toattempts to restore service to as many unfaulted sections of the feeder aspossible via the available sources. Torestore feeder sections, the feeder must be bothering least one backup sourcewith sufficient capacity to bear the additional load. A method based on the backup feeder loadbalancing is proposed and software is developed. The service restores software obtains thedistribution operation data from distribution automation system (SCADA) and thefeeder parameters from power grid production management system (GPMS). Then compares that loads with the sparecapacity for backup sources and bring out the service restoration plan for thedispatch staff.

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.

Nowadays, smart meters are widely used in power grid, which plays an important role in building the smart power grid and its stability is the key to stable operation of the grid. However, the reliability prediction of the smart meters is difficult to be performed due to its huge number and it cannot be tested one by one. In order to study the prediction method, according to the working principle of smart meters, this paper presents a simulation smart meter model based on Matlab/Simulink software. And related experiments are performed to measure the power consumption under different loads, through comparing the measured power consumption between the simulation model and power analyzer, the correctness of the presented model is verified.
