(1) in the real-time burden with power of line computation 10 KV electricity consumption industry, utilize step 2(3) in a certain 10 KV electricity consumption industry ratios obtaining be multiplied by step 3(1) in the real-time power load of same 10 KV that obtains, obtain the real-time burden with power of this 10 KV electricity consumption industry, method according to obtaining the real-time burden with power of this 10 KV electricity consumption industry, obtains step 1(1) the real-time burden with power of listed 10 KV electricity consumption industry;
(2) in the real-time burden with power of line computation 220 kv substation electricity consumption industry, by this step 4(1) in whole 10 KVs of obtaining the identical real-time burden with power of electricity consumption industry attribute be added, can be in the real-time burden with power of line computation 220 kv substation electricity consumption industry;
The online real-time statistics of (3) 220 kv substation electricity consumption industry composition, utilize this step 4(2) in the real-time burden with power of 220 kv substation electricity consumption industry that obtains divided by step 3(2) in the in real time total power load of 220 kv substations that obtains, can realize the online real-time statistics of 220 kv substation electricity consumption industry composition.
