[0102] Example

[0103] under Image 6 It is a schematic diagram of the application of a new type of power real-time calculation of intelligent power balance method in a power plant. The power balance is used to replace the power balance for the generator group, 10kV auxiliary section A section, 10kV auxiliary section B section, and 10kV desulfurization section bus respectively. System unbalanced power and unbalanced rate.

[0104] Take the generator-transformer group of a power plant as an example:

[0105] ①The power balance is as follows:

[0106] (P(t)g-P(t)n)=(P(t) 1 +P(t) 2 +P(t) tl +ΔP(t)t+P(t) 3 )+ΔP(t)l1

[0107] ②The unbalanced power is calculated as follows:

[0108] ΔP(t) f =(P(t)g-P(t)n)-((P(t) 1 +P(t) 2 +P(t) tl +ΔP(t)t+P(t) 3 )+ΔP(t)l1)

[0109] among them:

[0110] ΔP(t) f ——Unbalanced power, kW;

[0111] P(t)g——Generator active power, kW; see item 1 in the table below.

[0112] P(t)n——outlet (on-line) active power of main transformer, kW;

[0113] P(t) 1 ——High-voltage vari...

Abstract

The invention discloses a novel intelligent electric quantity balance method adopting power real-time operation. The novel intelligent electric quantity balance method comprises the following steps of setting up a mathematic model; establishing computing methods of active power and active electric quantity; carrying out electric energy information collection and electric energy balance on multifunctional electric energy meters in sub-regions and sub-systems according to house supply distribution characteristics of a power plant or a power station and a power distribution system; after the collected data of the multifunctional electric energy meters is processed, transmitting the data to a data analyzing and processing area by an optical fiber, and carrying out secondary processing by an electric energy efficiency on-line monitoring and management system to provide front-end display, analysis and printing. According to the novel intelligent electric quantity balance method, the electric energy balance precision is improved, the electric energy balance efficiency is increased, and the purposes of real-time on-line monitoring and real-time balance of the electric energy are met.

Description

technical field [0001] The patent of the invention relates to a new type of intelligent power balance method for real-time calculation of power, which is suitable for power consumption systems of different voltage levels in thermal power plants, hydropower stations, nuclear power stations and power distribution systems, and can be used for different buses, different power consumption equipment and systems, based on the new Real-time power calculation method, real-time, online, dynamic power balance function, suitable for online, remote, intelligent electric energy efficiency management system, fine management of electric equipment and online real-time balance function of electric energy. Background technique [0002] Electric energy balance is to study and analyze the distribution and utilization of a certain amount of electric energy after it enters the power consumption system, that is, how much power is effectively used and how much power is lost in each link of the power ...
