The invention discloses a decision-making method for adaptability evaluation of distribution network fault line selection, which comprises step 1 establishing various influence factors for distribution network fault line selection modes; step 2 measuring the influence factors under different dimensions According to different line selection methods, a unified positive evaluation index is formed; in step 3, the evaluation index of each line selection method is normalized, the maximum value of the index constitutes an ideal sample, and the minimum value of the index constitutes a negative ideal sample; Step 4 makes an evaluation decision based on the ranking of line selection indicators; it solves the problem that when selecting lines for distribution network faults, factors such as distribution network structure, outgoing line type, and load conditions will have different degrees of influence on different line selection methods; At present, there is a lack of research on the comprehensive evaluation of line selection methods. It is impossible to select the most optimal line method for the specific structure of the distribution network, and it is impossible to ensure the accurate selection of fault lines, which threatens the safe and reliable operation of the distribution network and other technical problems.

The invention discloses a method for evaluating the safety adaptability of unit operation in the primary frequency regulation performance test of thermal power units, belonging to the field of automatic control of electric power systems. It includes three sub-assessment methods: unit steady-state characteristic assessment, unit dynamic characteristic assessment and unit low-frequency oscillation risk assessment. According to the WAMS data uploaded by the power plant through the PMU, through state comparison, model simulation, parameter identification, disturbance test simulation and other methods, it is ensured that the disturbance amplitude imposed by a frequency modulation performance test of the thermal power unit is limited within the safety boundary of the unit, so as to prevent the unit from Power oscillation, combustion instability, main machine vibration and other consequences occurred during the test, effectively ensuring the safety of power generation.
