Research positioning · beta.6

Compare overlapping functions without collapsing different claims.

ARVREL belongs to the broader field of software-defined and virtual protection, but its selected public release is specifically a transparent Windows engineering laboratory with closed-loop secondary injection, process-bus analysis, feeder and transformer protection, AVR/OLTC simulation, laboratory MMS, and reviewable evidence.

Reference challenge

Lightweight Virtual Protective Relay

Public bibliographic metadata identifies Abdulmueen Alrashide's paper Lightweight Virtual Protective Relay, presented at the 2024 IEEE Industry Applications Society Annual Meeting. The associated public dissertation abstract describes a virtualization approach that abstracts hardware and uses CPU isolation for application-based execution requiring security, speed, and reliability.

Bibliographic record

Abdulmueen Alrashide, “Lightweight Virtual Protective Relay,” 2024 IEEE Industry Applications Society Annual Meeting (IAS), pp. 1–6, 2024. DOI: 10.1109/IAS55788.2024.11023755.

The comparison below uses public bibliographic/dissertation-summary information plus current ARVREL source and documentation. It does not infer unpublished implementation details.

Current overlap

ARVREL covers multiple software-defined protection and control chains.

Research questionARVREL beta.6 answerEvidence route

Non-equivalence

ARVREL does not inherit deployment-oriented or calibrated-equipment claims.

ARVREL beta.6

Engineering laboratory

  • Windows desktop application
  • Human-reviewable UI and evidence
  • Source-visible deterministic logic
  • Generic behavioral relay/test-set timing profile
  • Virtual output only
  • No hard-real-time or calibration guarantee
Separate research/deployment claims

Not established by beta.6

  • CPU-isolated production execution
  • Real-time kernel or deterministic scheduler qualification
  • Bounded end-to-end hardware latency proof
  • Calibrated test-set uncertainty
  • Manufacturer-specific relay hardware equivalence
  • Operational GOOSE or physical trip output

Transformer Differential status

87T is now implemented; the remaining research question is fidelity depth.

Beta.6 includes multi-stream Transformer Differential evaluation with CT/rating/polarity/vector compensation, 87T restraint, 87T-HS, REF HV/LV with independent neutral/NGR inputs, H2/H5 security, context-gated external-fault/CT-saturation behavior, deterministic self-test, synchronized internal two-sided injection, and paired external SV analysis.

02Winding and CT normalization
03Vector-group compensation
04Differential/restraint quantities
0587T / 87T-HS / REF
06Harmonic and CT-security context
07Trust and evidence
Remaining boundary: this is a vendor-neutral behavioral model. Device-specific transformer relay equivalence requires measured manufacturer/hardware evidence.

Accurate current statement

What ARVREL can say in beta.6.

ARVREL implements a transparent virtual protection/control laboratory with closed-loop external-I/O timing, IEC 61850 Sampled Values analysis, feeder and transformer protection, AVR/OLTC simulation, laboratory MMS, trust gating, and deterministic software evidence. It does not claim calibrated test-equipment accuracy, manufacturer-specific hardware equivalence, CPU-isolated production deployment, hard-real-time guarantees, conformance certification, or operational output authority.
