Yadda yake hanyoyin kisa ga ci gaban karamin shirya?
Amsa tana da wani matsayin gaba-gaban kasa a cikin hanyar zuba saboda abubuwan inductive (inductance) ko capacitive (capacitance), wadanda ke shafi fuskantar current zuwa voltage. Tushen amsa a kan kididdiga masu metering shine:
Yawan Faktoring Power
Farkon Faktoring Power: A cikin hanyoyi da ke da inductive ko capacitive, ana iya samun farko a bayanai da current zuwa voltage. Wannan yake haɗa da farkon faktoring power (PF), wanda ake bayyana a matsayin yawan active power (kW) zuwa apparent power (kVA). Faktoring power mai yawa yana nufin cewa mafi yawan energy an amfani da shi don jiragen electric ko magnetic fields ba don aiki mai kyau.
Kididdiga Energy Da Ba A Amfani Da Shu Ba: Suna da wani banga da ake kiran amsa, wanda ya nuna cewa wata banga na energy ba a amfani da shi don aiki mai kyau (ba a yi conversion zuwa useful energy) amma a yi establishment of magnetic ko electric fields. Wata banga na energy ake kira reactive power (Reactive Power), wanda ake yarda a kVar. Reactive power ba suka yi conversion zuwa aiki mai kyau amma ana buƙatar transmission daga system ta power.
Tushen a Meters
Abuɓuɓu a Kididdiga: Meters masu electromechanical na zamanin ba za su iya samun abuɓuɓu a cikin tsarin kididdiga daban-daban. Saboda haka, su ne da ake fada don pure resistive loads, kuma yawancin phase angles a cikin tsarin daban-daban za su iya haɗa da kididdiga mai sauransu.
Gaskiya ta Meters Masu Digital: Meters masu digital na zamani suna da aikace-aikacen don account for non-pure resistive loads kuma suke iya kididdiga active power da gaskiya. Amma, hatta meters masu advanced sun buƙata calibration mai inganci don hakkin gaskiyar kididdiga a cikin yawan reactive power mai yawa.
Tushen a Billing
Yawan Electricity Costs: Companies masu power suna iya yi adjustment a cikin billing based on the user's power factor. Idan faktoring power na mutum yana ƙoma a cikin limit, zai iya samun additional charges, saboda companies masu power sun buƙata extra equipment don handle reactive power.
Farkon Return on Investment for Equipment: Don industrial users, faktoring power mai ƙoma yana nufin inefficient utilization of power equipment (such as generators, transformers), wanda yake haɗa da farkon return on investment for the equipment.
Solutions
Don kawo tushen amsa a cikin kididdiga masu metering, za su iya yi wasu masu aikin:
Correction of Power Factor: Yi improvement of the power factor through methods such as adding parallel capacitors, wanda zai haɗa da proportion of reactive power kuma zai enhance the accuracy of energy metering.
Amfani da Meters Mai Dabam: Zabi meters da suka da dabam don non-pure resistive loads don hakkin kididdiga mai gaskiya.
Optimize Load Configuration: Arrange loads efficiently to minimize the generation of reactive power and improve the overall efficiency of the system.
In summary, the presence of reactance can lead to a decrease in the power factor, thereby affecting the accuracy and economics of energy metering. By taking reasonable steps to improve the power factor of the circuit, these negative effects can be effectively reduced.
