Class MeasMgr

java.lang.Object

com.powerdata.openpa.se.MeasMgr

public class MeasMgr
extends java.lang.Object

Manage the set of available measurements for the state estimator. Provides a well-defined iteration order for measurements and estimates. Also provides specific implementations for estimated measurement differences, and the measurement jacobian.

Measurements are ordered as:

1. from-side active power
2. to-side active power
3. bus active power injections
4. from-side reactive power
5. to-side reactive power
6. bus reactive power injections
