The Time Synchronization of Cost Control Electricity Meter Uncertain the Information Security Interaction Mode
With the increasingly application of TOU in electricity market, the electricity meter has higher requirements for the accuracy of the built-in clock. Aiming at the problem of clock inconsistency in electricity meter based on TOU, this paper proposed a time synchronization of cost control electricity meter uncertain the information security interaction mode. Firstly, By analyzing the reason of clock inconsistency of the cost electricity meter, the “master station-metering terminal-electricity meter” and “master station-electricity meter” layered design are presented. Secondly, taking the information security interactive mode of cost control electricity meter into consideration, two time synchronization methods are proposed. Finally, the two time synchronization methods are used to analyze the clock adjustment effect of cost control electricity meter clock, and used to compare with the traditional time mode. The engineering test results show that the two proposed methods have better complementary characteristics. The combination of the two methods can achieve the clock synchronization of the power-controlled energy meter well, and have wide application prospects, which have wide application prospects.
