Modeling the Bulk Electric Power System in ASPEN and CAPE
Evaluating the existing protection system and identifying the required relay upgrades in the system
Performing fault studies and coordination studies in developing relay schemes best suiting to the system
Relay Mis-Operation analysis
Experience in developing the relay settings for

  • Line Protection – Distance or Differential protection, DCB or DCUB scheme, via Fiber or PLC, understanding of applicable NERC/FERC regulatory requirements
  • Transformer Differential Protection
  • Bus Protection
  • Breaker Control – Breaker Failure, Sync and Reclosing
  • Capacitor Protection
Extensive experience in developing settings for modern microprocessor or legacy relays.

Database Cleansing and re-synchronization.

CompuSharp Profile - RTU and SCADA

CompuSharp has Engineers with experience in working in managing hardware and software configuration of several types of substation automation devices including GE RTU’s D20, D200, D25, D400 substation gateway or data manager and SEL and ORION communication processors.
The experience includes:
Configuration of Orion communication processor involving configuration of ports, addition of all the relay data points and logic operations in Orion. The logic operations on any input and output point and the configuration in the Orion is done using NovaTech Communication Director.
The RTU configuration involves:

  • Updating RTU database with I/O peripherals and relay data points.
  • Setting new communication channel for the communication processor which collects data from the relays.
  • Different protocol configuration for data collection application and data processing applications in RTU like DNP3, Modbus, S9000, 8979.
Configuration of D400 involving adding all the data points communicating on different protocols from various substation devices like RTU, IED, relays and system communication status points.
Configuration of data in D400S is categorized in to Analogs, Status, SOE, counters, Digital outputs, analog outputs, and alarms.

CompuSharp's greatest strength is its technical depth and experience in the field of design, implementation, project management, and servicing of SCADA and EMS systems. In particular, our engineering staff has extensive experience in analysis, development, customization and implementation of EMS applications. Some of the recent contributions of CompuSharp personnel are:

  • Relational DB customization and maintenance
