Provided are a novel distribution automation system and its voltage control method, which can supply a stable voltage to a user by properly adjusting the settings of a control device so as to compensate for reactive power at each load terminal. The voltage control method includes: a first step of modeling a distribution system in the form of a distribution load based on constants of four terminals according to the connection type of each node and a distribution line, which constitute the distribution system; a second step of determining a formula for estimating the magnitude of a voltage at a node from a current value of an adjacent node; a third step of determining an objective function including the magnitude of the voltage, calculated through the formula determined in the second step, and a control variable for controlling the magnitude of the voltage; and a fourth step of calculating a value of the control variable to allow the determined objective function to have a minimum value and applying the calculated value to each voltage control device provided in the distribution system.

A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and an organic solvent. Based on 100 parts by weight of the non-aqueous electrolyte solution, the non-aqueous electrolyte solution includes 1 to 5 parts by weight of sultone compound having a carbon-carbon unsaturated bond in a cyclic structure; 1 to 5 parts by weight of cyclic carbonate compound with a vinyl group; 5 to 10 parts by weight of cyclic carbonate compound that is substituted with halogen; and 1 to 5 parts by weight of dinitrile compound. This non-aqueous electrolyte solution improves stability of a SEI film formed on a surface of an anode of a lithium secondary battery and thus improves normal temperature cycle performance and high temperature cycle performance.

摘要:
A mobile terminal having a touch screen or a touch pad is disclosed. In a user environment, when a displayed menu list is moved according to a flicking operation, a feedback indicating the reaching of the end (the last item) of the menu list is issued in a visible, audible or tactile manner to a user, thereby increasing the user convenience of menu searching and the durability of the mobile terminal.
