CYME Power Engineering Applications for Distribution Network/System Analysis
Distribution Analysis
(CYMDIST)
To perform several types of analysis on balanced or unbalanced three-phase, two-phase and single-phase systems that are operated in radial, looped or meshed configurations. CYMDIST includes a full Network Editor as well as
– Unbalanced load flow
– Comprehensive fault flow analysis
– Load balancing
– Load allocation/estimation
– Optimal capacitor placement
Advanced Project Manager
Supports the collaborative and detailed preparation of a project that consists in modifications to the network with related simulations.
Automated Network Forecast Analysis
To create, view and modify time-dependent projects (using the CYME Advanced Project Manager) consisting in modifications to the network such as the addition of any load at a given date, change/replacement of power transformers within a substation, a rephasing/reconductoring project, network switching or reconfiguration, etc.
Steady State Analysis with Load Profiles
To perform accurate time range analysis based on a combination of AMR data and historical consumption patterns.
Distribution State Estimator
To analyze the unbalanced power flow and the voltages at every level of a distribution power system.
Reliability Assessment
Provides a framework within which predictive and historical reliability assessment scenarios are run and the impacts of the related investment such as DA (Distribution Automation) can be evaluated and understood.
Techno-Economic Analysis
Facilitates the evaluation of the feasibility and the profitability of a project based on the factual system model.
Transient Stability
To simulate the dynamic behavior of distribution systems with distributed generation under various transient events (fault application/clearing, large motor starting, disconnection of co-generation units, islanding, etc.)
Harmonics
Performs harmonic penetration analysis in electric power systems. It features single phase and full three-phase modeling capabilities and includes a large library of pre-defined models for network equipment and harmonic current sources.
The Frequency scan capability included in this module is also available as an independent module. This analysis provides full impedance scan results and allows the user to see problematic areas even before installing harmonic devices.
Long-Term Dynamics Analysis
Time-series simulation to study the impact of irradiance variations, wind fluctuations and load variations on network controls such as regulators, load tap changers and switched capacitors, and on the behavior of battery energy storage devices.
Integration Capacity Analysis
Addresses DER and load interconnection issues by determining the maximum allowable capacity that can be added at any point of the network without violating a set of constraints. Allows to quickly assess the hosting capacity of the network and filter out interconnection requests that are non-compliant.
EPRI DRIVE™
The calculation method provides aggregate and granular hosting capacity results for each distribution feeder and considers numerous circuit-specific attributes.
DER Impact Evaluation
Assists engineers in their generation interconnection system impact studies. The analysis automates a series of time-consuming, repetitive and error-prone verifications and returns insightful results that clearly identify violations.
Network Disturbance Assessment DA-CH-CZ
To determine the acceptability of a new load or generator interconnection by evaluating its impact on a series of power quality criteria.
Distance Protection Analysis
Helps engineers design and verify their protection scheme, and address different coordination issues in any power system.
Volt/VAR Optimization
Module that assists in finding optimal settings for Volt/VAR control devices to optimize distribution networks.
Optimal Voltage Regulator Placement
Allows the installation of voltage regulators at optimal locations on a distribution feeder.
Optimal Recloser Placement
Designed to help engineers handle the complexity of the system reliability improvement issue.
Arc Flash Hazards
To analyze and promote the electrical safety for employees working on or near electrical equipment. It computes the necessary parameters required to assess the risk level and adopt the adequate safety procedures.
Two modules are available to address specific needs. One for distribution networks, with arc flash hazards calculations based on the NESC© 2007 standard, and the second one based on the NFPA-70E© and IEEE-1584™ standards to analyze arc flash hazards in industrial power networks.
