Voltage Quality Optimization In Low And Medium Voltage Distribution Grid

The voltage quality is an important guarantee normal operation of the power system, itmarks the level of power system operation and management, and affect the quality ofindustrial products and the level of people’s lives. Voltage deviation is an important indicatorof the voltage quality, it ’s a direct impact on the working condition and service life ofelectrical equipment, power loss and power system voltage stability, security and economicrelationship with the system running.This paper studies10kV+380V low voltage distribution grid voltage qualityoptimization problems, in view of the special nature of the distribution network, with a pushback on behalf of law before an improved flow calculation, and the application the JAVAenvironment under the open source library of graph theory JGraphT programming;optimization software development ideas and the graphical interface with the grid voltagequality, and related to the calculation of the specific analysis page design, the underlyingoperating explain. The raw data for use in low voltage distribution network input to thesoftware operational analysis, output to improve voltage deviation in under various pressureregulator measures the effectiveness and cost-effectiveness of, pursuant to which theregulator method suitable for the distribution network.Developed distribution network voltage quality optimization software graphicalinterface is simple and easy to operate user with Grid the fish fly Station F4head line instancevalidation, Panyu full The software runs fast, accurate results, to promote the use of value.
