Description

technical field

[0001] The invention relates to the technical field of reactive voltage in electric power systems, in particular to a reactive voltage optimization analysis method and system. Background technique

[0002] Voltage is an important indicator of power quality. Voltage quality has a direct impact on grid stability, safe operation of power equipment, line loss, industrial and agricultural safety, product quality, unit power consumption and domestic power consumption.

[0003] The reactive power compensation and reactive power balance of the power system are the basic conditions to ensure the voltage quality, and play an important role in ensuring the safety, stability and economic operation of the power system. However, the reactive power balance of the power grid is difficult to achieve at present, the reactive power load fluctuates greatly, and the reactive power management is relatively weak, which makes the voltage problem more serious.

[0004] In order to e...

Embodiment Construction

[0048] The present invention is described in detail below in conjunction with the accompanying drawings:

[0049] like figure 1 As shown, this application relies on the provincial company's reactive power and voltage professional analysis and evaluation platform and the municipal company's reactive power and voltage analysis and evaluation platform.

[0050] The working principle of the professional reactive power and voltage analysis and evaluation platform of the provincial company is as follows:

[0051] (1) This method uniformly calculates the grid reactive power and voltage provided by the provincial EMS system 1-4 and the first web server 1-10 of the prefecture-level company through the main server 1-3 of the professional reactive power and voltage analysis and evaluation platform of the provincial company , analysis, and unified storage of operation data, including: capacitor reactive inflow, bus voltage value, transformer active and reactive power value, transformer l...
