Saudi Arabian Grid Code May 2024

Operation and Maintenance Safety Conditions 2.5.3.1 All Users responsible for the operation and maintenance shall also be responsible for the Safety of Equipment, persons, and facilities at their respective sides connected to the Transmission System. On Safety issues, Users shall follow the procedures as laid down in section 4.10 of Chapter 4: Operating Code and the Safety Rules referred to in that section. 2.5.3.2 Site Responsibility Schedule as provided in (2.7.5) will specify the ownership responsibilities of each User connecting to the Transmission System for the following: (i) ownership of the Plant/Equipment; (ii) the responsibility for operation and maintenance; (iii) Safety Rules and Procedures; and (iv) control of Plant/Equipments and facilities at their respective side. Chapter 2 - Connection Code The Saudi Arabian Grid Code Updated Version: May 2024 2.5.4 Metering Metering Equipment shall be installed at Connection Points in accordance with the provisions of the Connection Agreement and the standards defined in Chapter 7: Metering Code. 2.5.5 Requirements for Generators 2.5.5.1 All Synchronous Generating Units shall be capable of supplying rated Active Power output at any point between the limits 85% Power Factor lagging and 95% Power Factor leading at the Generating Unit terminals, unless otherwise agreed expressly by the TSP in the Connection Agreement. All Power Park Modules shall be capable of absorbing or supplying reactive power output at the connection point within the range Q = [-0.33, 0.33] of rated active power for Active Power output above 20% of rated power, unless a lower value of Active Power threshold is agreed upon expressly by the TSP in the Connection Agreement. Power Park Modules shall be capable of limiting reactive power output at the connection point within the range Q=[-0.05, 0.05] of rated power for Active Power output below 20% of rated power, unless a lower value of Active Power threshold is agreed upon expressly by the TSP in the Connection Agreement. Figure 2.1 P-Q Diagram 2.5.5.2 All Generating Units must be capable of continuously supplying their rated Active Power output at the Connection Point within the System frequency P in p.u. Q/Pmax Underexcited Operation (leading) Overexcited Operation (lagging) Cos(phi) = 0.85 Cos(phi) = 0.95 SGU PPM Chapter 2 - Connection Code The Saudi Arabian Grid Code Updated Version: May 2024 range 59.5 to 60.5 Hz. Any decrease of Active Power output occurring in the frequency range 57.0 to 59.5 Hz should not be more than a proportionate decrease in the frequency as long as it is not higher than 4%/Hz. Figure
