Sampling period is shorter, such as the two meets inverse relation, and sampling period T meets following formula:
The relationship in sampling period and electric energy exception probability is adjusted by adjusting the value of parameter k and C.
In other examples, the preset monitoring strategies refer to:
If any one in the current value at current time, voltage value exceeds corresponding highest limit value, processor module
The energy parameter to monitoring server 30 of several of 13 acquisitions of electric energy metering modules 11 transmitted and received in real time；
If any one in the current value at current time, voltage value beyond corresponding given threshold but is not out
Corresponding highest limit value calculates state with energy overall score, and
1) it is greater than the scoring threshold value of setting in response to state with energy overall score, processor module 13 is according to the second sampling period
Driving sampling module 12 samples several that electric energy metering module 11 acquires with energy parameter, and sampled result is real-time

Several that electric energy metering module 11 acquires are sampled with energy parameter according to third sampling period driving sampling module 12, and
And sampled result is sent to monitoring server 30 in real time；
Otherwise, processor module 13 acquires electric energy metering module 11 according to the first sampling period driving sampling module 12
Several are sampled with energy parameter, and sampled result are sent to monitoring server 30 in real time；
Second sampling period is less than the third sampling period, and the third sampling period is less than the first sampling period.
This mode by the current value, voltage value and state with energy overall score that are affected to electricity consumption situation as
The evaluation factor of monitoring strategies.
The mode that one of which calculates state with energy overall score is as follows:
The monitoring server 30 receives the sampled result that processor module 13 is sent, and calculates the side of state with energy overall score
Method the following steps are included:

ρiIt is the power quality scoring at the i-th moment, σiIt is the new energy electricity accounting at the i-th moment.
According to following formula to calculate state with energy overall score S:
Wherein, ω1、ω2、ω3Respectively electric current, voltage, active power weight factor, ω1+ω2+ω3=1.
Power quality can be realized by the power quality analyzer being arranged in ammeter, and power quality analyzer is surveyed
Corresponding standard value and weight factor is respectively set as affecting parameters in the power quality parameter measured, by method of weighting with
Calculate power quality scoring.
In some instances, it is contemplated that cost and power consumption are not provided with power quality analyzer in ammeter, then can basis
Following formula are to calculate state with energy overall score S:
Wherein, ω1、ω2、ω3Respectively electric current, voltage, active power weight factor, ω1+ω2+ω3=1.
It should be appreciated that the mode for calculating the sampling period, which is not limited to above-mentioned several but new sampling periods, should at least meet
Effective monitoring rate, that is, preset efficient threshold value should be greater than to the success rate prediction of abnormal conditions.
Specific embodiment two
