2. OBJECTIVE

Home is not just the building we live in, it is the whole planet with its streets, forests and deserts.

This is why it is not to be used temporarily for several years but for us and all the future generations, used with absolute care and attention.

3. PROJECT: A 48 MW INDUSTRIAL PARK

  • Location: At Suez
  • Consists of:

- 6 plants 40 MW total

- Services (lightings, Siharbor, gas stations…etc) 8 MW

  • This presentation contains 2 major topics:

3.1: HV S/S

3.2: Microgrid

7 of 49

3.1: HV S/S

  • Design digital substation 4.0 the future of grid IEC61850 known for: availability, efficiency and sustainability of the grid
  • Digitalization in substations means increased operational efficiency through use of new technologies, methods and processes delivering benefits around investment and operating costs
  • Components and protocol of digital substation 4.0: - Siprotec 5 protection relay - substation controller - HMI and SCADA system - IoT/IoE and cloud

3.1.4: SUBSTATION CABLES (LINE DIFFERENTIAL PROTECTION)

Transformer:

Rated less than 0.5 MVA protection is High voltage fuse

Rated above 0.5 MVA (Buchholz relay )

For rated above 5MVA ( diff protection

Relay siprotec5 7UT8 )

Depending upon the normal service condition, nature of transformer faults, degree of sustained over load, scheme of tap changing, and many other factors, the suitable transformer protection schemes are chosen
