Abstract In this paper, an optimal location strategy of voltage dip monitoring network based on line sectionalizing method is proposed. The remaining voltage expression of each bus is derived when a balanced or unbalanced fault taking place in any position of the complex power grid. All lines are sectionalized by using the remaining voltage expression and voltage dip threshold value. The voltage dip observability matrix covered the whole power grid is obtained. The number of monitoring devices and location place in the best monitoring network are derived by using genetic algorithms based on the observability matrix. The optimal monitoring network ensures that any fault leading to a voltage dip is recorded by at least one monitoring device. The validity of the proposed strategy is proved in the standard IEEE-30 bus system.

Key words： Voltage dip line sectionalizing observability matrix optimal location genetic algorithm balanced and unbalanced fault
