The invention discloses a centralized FA planning function detection method based on simulated transmission. The method simulates actual fault occurrence, fault diagnosis, fault isolation, and fault recovery processes based on DAS own distribution network topology model analysis, a FA simulation function module, a communication system, and a field automation distribution terminal, and monitors and analyzes the whole failure treatment process based on a main station FA planning detection module, and ultimately achieves centralized FA function detection. As a distribution automation project acceptance tool and a daily system testing and maintenance means, the method achieves a low-cost normalized FA planning testing purpose.
