PowerEngine and Electrical Studies

Fixed the Self-Healing module so that the criteria to choose the solution Most current left on the worst Switch ignores Switches with equal currents, ensuring the right choice for the solution. This bug occurred since v4.7.199.

Fixed the return code of the Self-Healing module to kSelfHealingResultMissingCurrentInformation when the Switch that triggered the trigger is having a problem referring to its current sample. This bug occurred since v4.7.119.

Fixed a failure in the Self-Healing module that allowed overloading and energizing of defective blocks in scenarios with parallelism enabled. This bug occurred since v4.7.119.

Fixed a failure that occurred when starting an application with any invalid value in at least one of the following Measurements of the Self-Healing module: SelfHealingRestorationTrigger, SelfHealingOverloadTrigger, SelfHealingNextStepTrigger, or SelfHealingCurrentLimit. This failure caused a restart of electrical modules. This bug occurred since v4.7.262.

The State Estimator module now correctly loads networks with connectors between devices with different parents. This bug occurred since v4.7.119.

Output three-phase power Measurements of the State Estimator module now can be correctly used. This bug occurred since v4.7.119.

Fixed a failure in the Power Flow module that prevented its functionality when there were islands with only one Busbar and some impedance in short-circuit. This bug occurred since v3.5.166.

Changed Electrical Studies so that Measurements without a change in value or quality are not propagated to data objects. This bug occurred since v4.7.119.

Fixed the current calculation in Switches on certain cases of parallelism of logical devices. This bug occurred since v3.5.81.

Fixed the Power Flow module with wrong values when there are Generators disconnected. This bug occurred since v4.7.156.

Fixed the Self-Healing module, which incorrectly ignored the limit of current in Switches not available and without current samples. This bug occurred since v4.7.119.

The State Estimator module is executed correctly (does not diverge early) if very large system Measurement variations occur. This bug occurred since v4.7.198.

The State Estimator module now uses as input the average of values of voltage Measurements registered in devices with different types (shunt and series) connected on the same Busbar. This bug occurred since v4.7.198.

Fixed the Self-Healing module, which allowed Switches with overloading to accept even more load during the execution of a maneuver plan. This bug occurred since v4.7.119.
