The 20 kV petalshape distribution network in SinoSingapore Guangzhou Knowledge City is introduced

and its characteristics that has several resources in the internal network but only one external resource in the power supply substation is analyzed. According to the requirement

a recovery control scheme for the petalshape distribution network based on the distribution management system’ graphical modeling tools

operating information and state estimate algorithm is proposed. The recovery scheme includes information validity checking

fault identification

recovery strategy calculation and execution

which can eliminate the influence of bad information

identify the fault type

choose the standby resource

cut off the over load and recovery the power supply automatically. Some necessary errorprevent measures are also proposed to improve the reliability. The recovery control functions are proved by the laboratory simulation test

and its reliability is analyzed with the typical telecontrol information.
