Embodiment Construction
[0034] Below in conjunction with embodiment, the present invention is further illustrated in detail.
[0035] refer to figure 1 , the calculation method of distribution network line loss based on load distribution coefficient and current equivalent time, the steps are as follows:
[0036] Step 1. Obtain real-time current data at the head end of the line: T Indicates the running time of the distribution transformer, Δ t represents the current sampling time interval, in T=N* Δ t Get N current values in time I i . Taking the electric energy metering system as an example, the electric energy metering system generally collects a current value in 15 minutes, and a total of 96 current values per phase per day. I i ( i ∈ [1, 96]). Taking the specific distribution line of a company as an example, 96 data points of real-time current at the head end of the line on a certain day are obtained.
[0037] Step 2: Obtain the capacity, model parameters, measurement point locatio...
