Synchronous Condenser

A synchronous machine operating without mechanical load and supplying or absorbing reactive power. free translation - IEC 60050.

Synchronous Condenser in PSP-UFU​

The synchronous condenser is simply a synchronous motor operating without load on its shaft with the purpose of supplying or absorbing reactive power in the network. Regarding load flow, in PSP-UFU this element behaves identically to the synchronous generator, but its active power is entered into the solution algorithms with a negative sign.

Its parameterization for load flow, fault, and harmonics studies is identical to that of the synchronous generator.

:::warning Caution! The synchronous condenser has not been implemented in the stability study, and its presence in the circuit may cause errors during calculations.

Do not include this element for stability studies. Future versions of PSP-UFU will include this element in such studies. :::

:::tip Tip It is possible to use a synchronous generator with zero or negative active power to represent the synchronous condenser in stability studies. :::

Synchronous Condenser Data Form​

The image below shows the insertion/editing form for synchronous condenser data:

Synchronous condenser form in PSP-UFU

Name​

Identification of the electrical element. Any number of characters can be entered in the Unicode standard.

All PSP-UFU power components have this field.

Rated power​

Rated power of the condenser, entered in MVA, kVA, or VA.

This field is especially important if the "Use nominal power as base" option is checked.

Active and reactive power​

Active power (entered in W, kW, MW, or p.u.) and reactive power (entered in var, kvar, Mvar, or p.u.) of the condenser.

If the connected bus is PV, the reactive power value is ignored; if it is a reference bus, both entered values are ignored.

:::caution Attention! If more than one condenser is connected to the same bus, the reactive power values (in reference and PV buses) and active power values (in reference buses) are equally distributed, respecting the individual reactive power limits. :::

Maximum and minimum reactive power​

Maximum and minimum reactive power limits of the condenser for voltage control on PV buses. If these values are exceeded, the reactive power generated by the unit will be limited to the entered value, and the connected bus will be converted to PQ, no longer controlling the set voltage.

Use nominal power as base​

If this option is checked, the program will use the condenser's nominal power as the base for unit conversion, including those in the stability form; otherwise, the system base power is used.
