Takaitaccen Shunt Capacitor

Shunt capacitor yana nufin wurare da ake amfani da ita don zama power factor tare da bayyana capacitive reactance don kawo inductive reactance a cikin electrical power systems.

Power Factor Compensation

Shunt capacitors suna taimaka wajen zama power factor, wanda ya gina line losses da kuma yadda ake zama voltage regulation a cikin power systems.

Capacitor Bank

Capacitive reactance ana amfani da ita a cikin system da suka amfani da static capacitor a shut ko series da system. Ba a yi amfani da abu na biyu ga capacitor a cikin phase na system ba, amma an yi amfani da bank of capacitor units, saboda hanyar yanayin da kuma erection. Wannan group ko bank of capacitor units yana nufin capacitor bank.

Akwai mafi girman duwatsu na capacitor bank saboda hanyoyin connection arrangements.

• Shunt capacitor.

• Series capacitor.

Shunt capacitor yana amfani da ita da ma'ana ta musamman.

Connection of Shunt Capacitor Bank

Capacitor bank zai iya haɗa a cikin system a delta ko a star. A star connection, neutral point zai iya kasance ko ba saboda hanyar protection scheme for capacitor bank adopted. A wasu muhimmanci, capacitor bank zai farawa a double star formation.Gaskiya, large capacitor bank a electrical substation ana haɗa a star.

Grounded star connected bank tana da al'amuran da dama, kamar,

• Reduced recovery voltage on circuit breaker for normal repetitive capacitor switching delay.

• Better surge protection.

• Comparatively reduced over voltage phenomenon.

• Lesser cost of installation.

A solidly grounded system, voltage of all three phases of a capacitor bank take daidai, hata a lokacin two-phase operation.

Location Considerations

Ideally, capacitor bank yana bukatar da a haɗe karin reactive loads don kawo reactive power transmission across the network. Idan a haɗa capacitor da load, za su iya haɗa a lokacin da suka haɗa, tare da kawo overcompensation. Amma, ba zai bukatar ko zama economic ba a haɗa capacitor zuwa each individual load saboda varying load sizes and availability of capacitors. Kuma, not all loads are connected continuously, so the capacitors may not be fully utilized.

Hence, capacitor, ba a haɗa a small load ba, amma for medium and large loads, capacitor bank can be installed at consumer own premises. Although the inductive loads of medium and large bulk consumers are compensated, but still there would be considerable amount of VAR demand originated from different uncompensated small loads connected to the system. In addition to that, inductance of line and transformer also contribute VAR to the system. On viewing of these difficulties, instead of connecting capacitor to each load, large capacitor bank is installed at main distribution sub-station or secondary grid sub-station.
