Analyze and derive the relationship of each electrical quantity of the single-end fault location algorithm and present a fault location formula of two-end fault location algorithm. Through the simulation research of MATLAB/Simulink, when the fault occurs near in either end of the line, the ranging device near the fault point is adopted, fault distance can be measured with single-ended electrical quantities algorithm, when the fault occurred in near the midpoint of the line, two-end fault location algorithm is chosen to ensure the results’ accuracy higher.

This paper presents the highlights of the third annual edition of the BP Energy Outlook, which sets out BP’s view of the most likely developments in global energy markets to 2030, based on up-to-date analysis and taking into account developments of the past year. The Outlook’s overall expectation for growth in global energy demand is to be 36% higher in 2030 than in 2011 and almost all the growth coming from emerging economies. It also reflects shifting expectations of the pattern of supply, with unconventional sources — shale gas and tight oil together with heavy oil and biofuels — playing an increasingly important role and, in particular, transforming the energy balance of the US. While the fuel mix is evolving, fossil fuels will continue to be dominant. Oil, gas and coal are expected to converge on market shares of around 26—28% each by 2030, and non-fossil fuels — nuclear, hydro and renewables — on a share of around 6—7% each. By 2030, increasing production and moderating demand will result in the US being 99% self-sufficient in net energy. Meanwhile, with continuing steep economic growth, major emerging economies such as China and India will become increasingly reliant on energy imports. These shifts will have major impacts on trade balances.
