Data interface of stable calculation analysis simulation software BPA.

Description

technical field [0001] The invention relates to electric load modeling, in particular to an electric load modeling device based on real-time disturbance data. Background technique [0002] The power system load model is a mathematical equation and corresponding parameters that reflect the characteristics of the power and current of the load port of the actual power system with its port voltage and frequency. Load modeling not only establishes models for various specific electrical equipment components, but more importantly, studies the relationship between the power absorbed by the overall load on the load bus and the change of the load bus voltage and frequency, and describes the mathematical equations that determine this relationship form and its parameters. Digital simulation of modern power system design, planning, decision-making and operation requires a more accurate load model. Because the change of the load model has different degrees of influence on the system tra...
