Comprehensive reliability analysis of the enterprise power supply

Customer

  • Industrial Power Plant
  • Own generation (Mini-CHPP)
  • Availability of 1st class consumers
  • 80% motor load
  • Sharply variable load

Project goals

To develop measures ensuring stable operation of 1st class consumers of an enterprise, as well as stable operation of its own generation (Mini-CHPP) under the normative perturbations in the external and internal power network


Challenges

  • Stability and power supply violation of 1st class consumers
  • Own generation (Mini-CHPP) dynamic stability violation in case of external electrical grid disturbances
  • Incorrect operation algorithm of protection terminals for single-phase ground faults
  • Unsuccessful starts of large electric motors
  • The voltage drop is from 20 to 70% for a duration of 0.3 to 7 seconds in case of external electrical grid disturbances

Implementation

Reactive power balance optimization

fast acting emergency protection simulation and implementation

fast acting automatic transfer switch simulation and implementation

fast acting Power Factor Correction Units (PFCU) simulation and implementation

Automatic local voltage regulation system development

Dynamic compensator of voltage distortion simulation and implementation


Results

Reliability improvement

Power efficiency of Mini-CHPP operation increasing by means of the existing reserves

The possibility development to derive economic benefits from episodically arising low prices for electricity of the wholesale electricity market (up to zero) – the unique algorithm
