Quality analysis of energy and harmonic analysis based on frequency-domain load simulation models predict potential resonances and determine harmonic distortion levels. PGMEX performs analyses of several parameters, including:

• Voltage and current harmonic values (IEC 61000-3-6)
• Assessment of non-characteristic and higher harmonics
• Assessment of multiple harmonic sources: current, voltage, thyristor rectifiers, PWM converters, SVS, nonlinear loads
• Evaluation of harmonic distortion indices, THD, HD, HF, THF, TAD, TIFmx, effective total current and voltage values
• Harmonic distortion graphs with predefined limits according to IEC standards
• Flicker analysis
• Light flicker assessment (IEC 61400-21)
• Frequency analysis
• Own and mutual impedance/admittance analysis
• Automatic resonance identification
• Filter system analysis and selection

Connection feasibility studies involve comprehensive modeling of static and dynamic loads in relation to the connection point parameters and optionally specific sections of the RSO network. The behavior of all significant components operating dependently within a single Power Generation Module (PGM), particularly power generating units (PGU) within Power Park Modules (PPM), such as power electronic converters, compensation systems, dependent loads (e.g., electrolyzers, car chargers, thermal storages, fuel cells), filters, and electric energy storage systems, is examined. The aim of the connection feasibility study is to determine the parameterization of PGM components in a way that allows operation in compliance with Network Codes (NC), RSO instructions, and connection conditions. PGMEX supports cases including:

• Shared connection by different power generating units (PGU) within one Power Park Module (PPM) – so-called Cable Pooling
• Modifications of existing PGMs through equipment replacement, system expansion, or re-parameterization of components
• Dependent generation and consumption units operating at the connection point (e.g., generation, battery storage electrolyzers, car chargers).
• System optimization aimed at increasing production efficiency

Connection feasibility studies, particularly for new PGMs, can be implemented at the conceptual stage of the investment, aimed at achieving optimal parameters and selection of components.

PGMEX performs electrical installation designs and comprehensive analyses, including short-circuit current calculations, stability analyses, and network configuration assessments to optimize and ensure compliance with industry standards and specific project requirements.

For specialized or detailed assistance, please provide additional information on your specific needs or project scope, and we will tailor our support to ensure the best outcomes for your power generation module or energy facility.

Distribution and transmission networks are constantly exposed to fast and slow transients. Lightning discharges, switching operations, and short circuits lead to short-term voltage increases that can exceed the permissible levels of BIL (Basic Insulation Level) or TOV (Temporary Overvoltage) for working transformers, cables, switchgear, and other components of the power system. Proper insulation coordination, appropriate selection of surge arresters, or the use of switching synchronization can significantly reduce the risk of potential transient failures.

At PGMEX, we perform EMT (Electromagnetic Transients) analyses, which include:

• Determining transformer inrush current,
• Switching on and off capacitor banks,
• Insulation coordination according to IEC 60071,
• Switching operations on overhead and cable lines,
• Switching operations involving vacuum and SF6 circuit breakers,
• Fast transients resulting from lightning discharges,
• Resonance involving transmission lines and compensating reactors,
• Ferroresonance involving transformers and voltage transformers,
• Selection of surge arresters.
