Power Regulation Solutions are specifically designed to meet the challenges of mixed park regulations where different renewable energy plants are designed to be the only one receiving the set points.
Power Regulation Solutions delivered by SCADA International are needed when:
CONTROLLING AND REGULATION OF MIXED PARKS - WIND FARMS AND POWER PLANTS
DEFINING SET-POINTS IN TERMS OF ACTIVE AND REACTIVE POWER
VALIDATING SET-POINTS IN TERMS OF ACTIVE AND REACTIVE POWER
For mixed parks where different OEM Renewable assets are designed to be the only one receiving the set points there are special grid code requirements defined by local utility companies and legislation.
To have the ability to control and regulate the mixed park as well as define and validate set-points in terms of active and reactive power it is needed to have a modern and customized Power Regulation Solution.
One of the most well-known Power Regulation Solutions in the market is the OneView® Energy Control Unit known as ECU. It is an advanced technology which controls the power output at the ''Point of Common Coupling'' (PCC) of either one or more energy producing units or compensation equipment units. By an energy unit we define a wind park, a capacitor bank, a single turbine, a wave power plant, solar panels among other sources.
The system makes sure that energy units meet the specific grid code requirements and that all the data is logged.
Our Power Regulation Solutions may be used as the power regulation module of a OneView® SCADA solution or the OneView® Energy Control Unit could be equipped with a local or a remote light version of the OneView® SCADA system for live data monitoring and reporting.
Furthermore, it can be used as a stand-alone solution as well. This is convenient when the numerous types of data are accessible on an open communication interface and therefore could be incorporated into any SCADA system.
The commanding signals of the energy units (sub-units) are calculated on the basis of the regulation algorithm, the received energy set points and the actual measurements at the ''PCC'. These regulation methods are supported by:
|- Cos phi control|
|- Voltage control|
|- Frequency control|
|- Active power ramping|
|- Active and reactive power control|
Besides the standard control algorithms, site specific controls can be implemented to meet any requirements, such as control of substation equipment, event triggered controls (shadow, noise, wind speed etc.) or handle the controls according to different time schedules.
Reactive power set points can be distributed to sub energy parks based on possible capacitive/inductive capability of each sub energy park. The reactive power regulation can run both Q-ref mode or Cos phi mode.
System communicates directly with the power plant and supports several regulation methods.
It consists of a basis OneView® ECU solution with optional add-ons: OPC interface, Modbus interface, Power meter, UPS back up, OneView® ECU Outdoor Solution and many more.
The ECU may be equipped with a local or a remote version of the OneView® SCADA system for live data monitoring and reporting. Furthermore, it is certified by GL.
OneView® ECU reports:
|- Cos phi report|
|- Lost production report|
|- Active and reactive power report|
Power Regulation Solution user gets an ability to monitor and control wind farms and power plants in a way that fulfils specific grid code requirements from utilities.
It brings production portfolio assets together in one control unit and optimizes power production and earnings.
May be used as a stand-alone solution or integrated with OneView® SCADA delivered by SCADA International.
