Research Of Comprehensive Residential Buildings’ Electricity Load Calculation And Design Of Supply And Distribution System

In the electrical design,the electrical load calculation affects the Selection and design of distribution facilities and the operation of electrical equipment,the electrical safety and personal safety.Currently,the general electric residential load calculation method is demand coefficient method,According to the residential area to determine the load index Therefore,whether the load calculation is right or not,the key lies in the accuracy of the calculation load and the select the required coefficient,but the existing residential electrical design specifications are according to the construction area to determine the residential load,this load calculation methods exist drawbacks,and it does not consider the specific problems,so how to accurately determine load index of residential units and how to scientifically select the desired coefficient of electrical engineering design has become a hot issue.Aiming at the shortcomings of traditional load calculation method,the proposed application of regression analysis to calculate the load index of residential units to predict and calculate.And conducted in-depth research,mainly to do the following works:1)This thesis selected typical residential building,through research the amount of household appliances,and its power usage,analyze the relationship between the amount of household appliances and residential load calculation,according to the sample data,ultimately proposed that electrical power equipment is the mainly compose of the computational load of the housing units.Establish appliances power as independent variable,residential load calculation unit as the dependent variable,establish the Load Forecasting Model.2)Consider the Particularity of Load index calculation unit forecast,In this thesis,several types of load forecasting method were analysed,we analyzed their shortcomings and advantages,and accordance to the actual situation,determined using regression analysis to calculate the residential unit load forecast;3)According to the acquired sample data,a prediction model based on computational load index regression analysis of residential units;4)Residential Load Calculation prediction model are based on regression analysis,and Comprehensive residential building projects load forecast calculation,According to the results of load calculation,calculate and select the power supply and distribution equipment and achieved good results;Compared to the traditional empirical methods,the proposed method improve the precision of load calculation.ensure the safe operation of equipment,achieved a unified whole project economy and stability.and achieved good results,meet the project design requirements.
