4. The pass is examined : The power supply quality (such as the electric current , voltage , wave in harmony , photo corner ) to a pass is analysed
5. Worthy of changing and monitoring: For working state of distribution network not whole (whether export voltage, electric current,gain merit, inactive power,etc.) go on not monitoring
6. Oppose electricity-stealing to analyse: Distribution system can realize the whole section or is it is it gather equipment to carry far to establish by stage , make up line loss monitor the network, actual loss and amount lost difference, analyse whether the circuit steals electric behaviors at any time
7. Load is predicted: Predict ahead of time the power consumption of a monitoring point with the job placement after being convenient
8. Whether small water local / electricity generation by thermal power surf the Net electric consumption is controlled , the line loss is analysed. Through monitor analysis of network to line loss , can control to each water , power consumption of thermal power station, prevent them from stealing the electricity in a large amount
9. Information sharing: The power consuming situation of every monitoring point can realize the information sharing through the network
10. Power consuming quality is monitored: Analyse through line loss gain merit , inactive power analyse , offer electric wire netting power consuming quality
11. Purchase the electricity in advance to control: Through the analysis to that load predicts , control purchasing electric consumption of the whole electric wire netting
12. Gain merit , there is no work to manage: Active power , inactive power to every monitoring point analyse , strengthen power consuming quality
13. The wave in harmony is analysed: Pass antithesis times of in harmony wave , strange times of in harmony analysis of wave (3 - 5 in harmony wave mainly ), strengthen the control on power consuming situation, improve power consuming quality
