Power analysis in power systems by simulation models and field tests: breakage root causes of transformers, thermal problems and breakages caused by harmonics, detection of potential electrical failures, etc.

Grid integration studies: Library models of “special” electrical machine for PSCAD. Models validated on manufacturer’s tests in electrical grids and with power converters. These models support multi-instance in the same case, in order to simulate a complete wind farm with different machines operating at different regimes.

A RMS model formed by several modules incorporate some controls techniques in order to emulate the behavior of the storage system in the compliance of different grid codes.

Differents events in the network are modelled, simulating the batteries storage system responses: energy charge flow, maximum currents, etc. and the consequences on their premature aging.

3. Modelling and simulation of PV plants.


Special electric machine models with multiple instance capacity. This particular process requires specific validation techniques for grid integration with manufacturer and converter parameters included. These models admit multi-instances against a single case, to simulate from a single machine to a whole wind farm with several turbines operating in different setups.

These models include their own numerical methods for equation integration, especially for STATCOMS, electric machines etc.

PSCAD LIBRARY MODELLING


We develop electrical, thermal and mechanical simulation models from detailed technical information, field tests, dia-grams, etc. to detect potential problems in power systems. The models allow you to analyse and determine the causes of breakage in transformers, as well as to detect thermal problems in wiring systems.

We analyse breakages caused by high frequency harmo-nics and other potential risks of electrical failure in the case of short circuits, and propose solutions. These models are developed in different platforms according to the needs and data of the client. We can evaluate installations with models in VBA, Excel, Visual C ++, PSIM, PSCAD, etc.

• Evaluation of power loss in DC cables and in MV AC circuit.

• Real time estimation of cable temperatures in different parts of the LV and MV circuits, considering weather conditions. Detection of the installation’s critical points and evaluation of the operating temperature.

O&M CONSULTING IN PV PLANTS


RELATED PROJECTS

1. O&M consulting in PV Plants. We perform a wide variety of studies for the most frequent problems in the operation of PV plants and Wind farms.

From the main installation indicators such as: power, generators, layout and location data we define the LV and MV electrical circuits of PV plants and wind farms. The DC and AC cables are dimensioned according to electrical criteria such as: maximum admissible current, voltage drop, power losses and particular characteristics of the country where the installation is made.

The earthing of the substation is evaluated to cover any type of fault in different parts of the electrical circuit, verifying that the step and contact voltages comply with regulations.

We check suppliers’ compliance with the specified requirements of the installation.

Our team develops tools in VBA in order to automatize and provide the calculus needed to manage each facility.

SUPPORT IN THE DEFINITION OF MEDIUM AND LOW VOLTAGE INSTALLATIONS


SIG leads an R&D project for the development of a microgrid management system with storage. The project began in 2018 and is scheduled to be completed in 2020.

Once the installation has been dimensioned, the management system will be able to control the loading and unloading of the batteries according to the projected generation and consumption.

The microgrid controller incorporates a learning system that will optimize the batteries management according to the differences between projections and the real data historics.
