Embodiment example

[0163] Implementation case: Taking the energy saving calculation of the substation reactive power compensation renovation project as an example, it is more appropriate to use the measured power factor calculation method for the site conditions.

[0164] According to the calculation formula, the parameters required for the final conclusion include the annual equivalent operating time, the dielectric loss tangent of the capacitor, the rated compensation power of the reactive power compensation device, the power factor before the transformation, the power factor after the transformation, and the maximum active power during the monitoring period after the transformation.

[0165] The parameters that must be input manually include the annual equivalent running time T=4000h, the dielectric loss tangent value of the capacitor tanδ=0.0008, and the rated compensation power Q of the reactive power compensation device c =2000kvar.

[0166] The parameters measured on site include the powe...

Abstract

The invention provides an energy saving calculation and analysis system for a power grid energy saving project. The system comprises a boost and line reconstruction module, a transformer replacing module, a reactive compensation module, a three-phase imbalance module and a harmonic control module, where the modules above are connected with a code table and calculation module. The system provides convenience for power grid energy saving project prophase planning and later-period evaluation as well as activities for carrying out measurement and verification on saved power and energy quantity of the power grid energy saving project required in the power demand side management and evaluation and the like.

Description

technical field [0001] The invention belongs to the field of energy efficiency evaluation, and in particular relates to a calculation system for power grid energy saving projects to save electric power. Background technique [0002] Boosting and line reconstruction, transformer replacement, reactive power compensation, harmonic control, and three-phase unbalance control are the most commonly used and most effective energy-saving and loss-reducing measures in power grid operation. At present, the power saving calculation of power grid energy saving projects mainly depends on the project evaluation personnel to select the corresponding formula to calculate according to the on-site situation, which is inefficient and prone to errors, and the preliminary analysis and evaluation of the project on the spot after the calculation is completed depends on the experience and experience of experts. Memory is also an uncertain factor in the conclusion of on-site evaluation. When the conc...
