Overview

DESCRIPTION

PMM1105 is a reliable and flexible solution capable of controlling a series of different elements present in PV and Wind power plants to achieve TSO (Transmission System Operator) or DSO (Distribution System Operator) requirements at the point of common coupling.

The international requirements for grid stability management are met using closed loop controls offering the following functionalities:

• Active Power Reference, with or without ramp rate limiter (increase or decrease power if it is possible)
• Active Power Curtailment, regardless of the presence of a ramp rate limiter
• Frequency control depending on the frequency deviations
• Voltage Control through an automatic voltage regulator
• Reactive Power control
• Power factor control

Data acquisition and control is inverter independent and gives feedback about losses due to inverter malfunction, PV modules soiling, shading and but not limited to module degradation.

This Windows based platform can control up to 200MW PV plants with just one controller meeting all international requirements and fulfilling IEC 60870-5 (communication protocol for supervisory control and data acquisition) standard for active power, reactive power, ramp rates, etc. Data collection rate can be down to one second or more, which is often required by utilities to zoom for grid impacts tests.

The strength of this flexible data solution is its ability to perform signal conditioning, data storage, transfer and compression. Communication is fast, easy and reliable as it uses the communication industry standard protocols (Modbus), longer distances can be reached effortlessly through fiber optic technology.
