Abstract
A kind of method calculating power grid electric using power integral of the present invention, is calculated using timing cycle and power integral method is used to calculate power grid electric.There are three advantages provided by the invention using with power integration method calculating power grid electric: the first, high-efficient due to being not necessarily to manual intervention using calculating automatically；The second, panoramic view data can be obtained, it can be to the electricity data for obtaining any moment in one day；Three, accuracy rate is high.
Description
Technical field
The present invention relates to power network schedule automation fields, calculate power grid electricity using power integral more particularly, to a kind of
The method of amount.
Background technique
It can not directly be collected in automation system for the power network dispatching at present in the market without measuring entire power grid electric number
According to, and power grid electric data are the data that dispatching of power netwoks mechanism is paid special attention to, these data used very in order to obtain in the past
Original method obtains electricity data from other departments by phone or mail first, will then be obtained by dispatching person on duty
The mode that is manually placed in of electricity data be injected into dispatch automated system, time-consuming and laborious, inefficiency.
Summary of the invention
It can not directly be collected in current automation system for the power network dispatching in the market to overcome without measuring entire power grid
The problem of electricity data, the present invention propose a kind of method for calculating power grid electric using power integral, the technology that the present invention uses
Scheme is:
A method of power grid electric is calculated using power integral, comprising the following steps:
S10. the current calculating time t2 in reading service device, current active power P and last computation time t1 in server；
S20. judge whether the time interval of t2 and t1 is greater than 24 hours, if then initializing total electricity is 0, otherwise continue to integrate
Cumulative electricity.
Preferably, it is described continue to integrate cumulative electricity it is as follows:
Q=Q+ΔQ；
Wherein Δ Q is to calculate time t1 to the electricity for calculating time t2 this period, Δ Q=p*(t2-t1)；Q is cumulative electricity.
Preferably, the calculating cycle is consistent with the active-power P update cycle.
Preferably, the clock system of the server uses GPS clock.
There are three advantages provided by the invention using with power integration method calculating power grid electric: the first, due to using
It is automatic to calculate, it is not necessarily to manual intervention, it is high-efficient；The second, panoramic view data can be obtained, it can be to the electricity number for obtaining any moment in one day
According to；Three, accuracy rate is high.
Detailed description of the invention
Fig. 1 is the flow chart for the method that power grid electric is calculated using power integral that this method provides.
