[0034] Embodiment 2

[0035] like Figure 2 As shown, a method for evaluating the operating efficiency of a power regulator based on data analysis comprises the following steps:

[0036] Step 1: Monitor and analyze the operating performance of the power regulator: generate a monitoring cycle, obtain the load data FZ, energy consumption data NH, instantaneous data SS and heating data FR of the power regulator at the end of the monitoring cycle, and perform numerical calculations to obtain the performance coefficient XN, and determine whether the operating performance of the power regulator meets the requirements through the performance coefficient XN;

[0037] Step 2: Test and analyze the response fault of the power regulator: set several test load values, adjust the load of the power regulator to the test load value for testing and mark the test load value as a response load value or a fault load value, mark the ratio of the fault load value to the test load value as a fault coefficient, and determine whether the power regulator has a response fault by the fault coefficient;

As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.

[0041] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula close to the real value. The coefficients in the formula are set by technicians in this field according to the actual situation; for example: formula XN = α1*(NH / FZ)+α2*(FR+SS); technicians in this field collect multiple groups of sample data and set corresponding performance coefficients for each group of sample data; substitute the set performance coefficients and the collected sample data into the formula, any two formulas constitute a binary linear equation group, screen the calculated coefficients and take the average, and obtain the values ​​of α1 and α2 as 4.32 and 2.17 respectively;

[0042] The size of the coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the coefficient depends on the amount of sample data and the preliminary setting of the corresponding performance coefficient for each set of sample data by technical personnel in this field; as long as it does not affect the proportional relationship between the parameter and the quantified value, such as the performance coefficient is proportional to the value of the energy consumption data.
