Facilities

The IEPG group owns the following research facilities and laboratories for its research:

The renewable energy laboratory DENLAB

DENLAB is an autonomously operating renewable energy environment that meets the energy needs of 10 households by wind and solar energy and a combined heat and power system. The system has 12kW (120 m2) solar panels installed, 30kW wind power (simulated by an anemometer and a motor-generator set), 5.5kW CHP (combined heat and power; simulated by a motor-generator set), 100kWh energy storage (simulated by a bi-directional inverter) and a grid -connection. The development of an Intelligent Power Control Unit - to run the system autonomously - is the main objective of the research.

A Real-Time Digital Simulator

RTDS at TU Delft consists of 8 racks supplied with 3PC cards that are able to be used for real time simulation with a time step greater than 50µs (to be upgraded via new PB5 cards to 2µs in 2015). The RTDS Simulator allows to test protection and controls in real time, where an hour in the real world equals an hour in the simulator. Utilizing modular custom computing hardware and software, simulations performed encompass results from DC up to electromagnetic transients. Inherently, these results include information regarding the system load flow and transient stability, as well as that of harmonics and faster disturbances.

Applications include

  • Equipment can be thoroughly test-driven and customized.
  • New power system network designs or upgrades can be evaluated and accurately tested.
  • Black box real-world equipment (e.g. closed-source controllers) can be tested and integrated in larger test scenarios without having a model.
  • Interoperability of multi-vendor installation can be validated
  • Models and real implementations (products) of components can be compared
  • Closed-loop testing of protective relays and control systems.
  • Studying general AC system operation including behavior of generation and transmission systems.
  • Investigating dynamic power system equipment interaction.
  • Studying interaction between integrated AC/DC systems.
  • Testing of control system of converter based equipment.
  • Integration and operation of distributed generation and renewables.
  • Investigation and testing of SMART Grid initiatives including wide area protection and control.

A High-voltage laboratory

 The High-voltage laboratory is the second largest in the Netherlands. Testing facilities include a 4 megavolt impulse generator and ac sources up to 1.5 megavolt.

Unique possibilities are offered to students and researchers enabling them to study full-scale high voltage equipment. For industry, tests are performed according to IEC 60060 ”High-Voltage test techniques”, like:

  • AC testing,
  • Impulse and switching impulse testing,
  • Corona and RIV testing,
  • Partial discharge testing,
  • Tangens delta testing

Additionally the laboratory is equipped with facilities for:

  • Dielectric spectroscopy
  • Space charge measurments
  • Thermal conductivity measurements
