Reactors Class

Initializes a new instance of the Reactors class

Array of strings with all Reactor names in the circuit.

Name of first bus. Bus2 property will default to this bus, node 0, unless previously specified. Only Bus1 need be specified for a Yg shunt reactor.

Name of 2nd bus. Defaults to all phases connected to first bus, node 0, (Shunt Wye Connection) except when Bus2 is specifically defined. Not necessary to specify for delta (LL) connection

Number of Reactor objects in active circuit.

Sets the first Reactor active. Returns 0 if no more.

Get/set active Reactor by index; index is 1-based: 1..count

Delta connection or wye?

For 2, 3-phase, kV phase-phase. Otherwise specify actual coil rating.

Total kvar, all phases. Evenly divided among phases. Only determines X. Specify R separately

Name of XYCurve object, previously defined, describing per-unit variation of phase inductance, L=X/w, vs. frequency. Applies to reactance specified by X, LmH, Z, or kvar property. L generally decreases somewhat with frequency above the base frequency, approaching a limit at a few kHz.

Inductance, mH. Alternate way to define the reactance, X, property.

Sets the active Reactor by Name.

Sets the next Reactor active. Returns 0 if no more.

Indicates whether Rmatrix and Xmatrix are to be considered in parallel.

Number of phases.

Resistance (in series with reactance), each phase, ohms. This property applies to REACTOR specified by either kvar or X. See also help on Z.

Name of XYCurve object, previously defined, describing per-unit variation of phase resistance, R, vs. frequency. Applies to resistance specified by R or Z property. If actual values are not known, R often increases by approximately the square root of frequency.

Resistance matrix, ohms at base frequency. Order of the matrix is the number of phases. Mutually exclusive to specifying parameters by kvar or X.

Resistance in parallel with R and X (the entire branch). Assumed infinite if not specified.

How the reactor data was provided: 1=kvar, 2=R+jX, 3=R and X matrices, 4=sym components. Depending on this value, only some properties are filled or make sense in the context.

Reactance, each phase, ohms at base frequency. See also help on Z and LmH properties.

Reactance matrix, ohms at base frequency. Order of the matrix is the number of phases. Mutually exclusive to specifying parameters by kvar or X.

Alternative way of defining R and X properties. Enter a 2-element array representing R +jX in ohms.

Zero-sequence impedance, ohms, as a 2-element array representing a complex number. Used to define the impedance matrix of the REACTOR if Z1 is also specified. Note: Z0 defaults to Z1 if it is not specifically defined.

Positive-sequence impedance, ohms, as a 2-element array representing a complex number. If defined, Z1, Z2, and Z0 are used to define the impedance matrix of the REACTOR. Z1 MUST BE DEFINED TO USE THIS OPTION FOR DEFINING THE MATRIX. Side Effect: Sets Z2 and Z0 to same values unless they were previously defined.

Negative-sequence impedance, ohms, as a 2-element array representing a complex number. Used to define the impedance matrix of the REACTOR if Z1 is also specified. Note: Z2 defaults to Z1 if it is not specifically defined. If Z2 is not equal to Z1, the impedance matrix is asymmetrical.

Returns the low-level handle of the current OpenDSS/DSS-CAPI instance.
