Frequency and voltage control of a high-penetration, no-storage wind-diesel system.

摘要

High-penetration, no-storage wind-diesel (H scPNSWD) is considered to be the most economical approach to implementing wind-diesel. In this thesis a detailed comprehensive dynamic model of a H scPNSWD system is presented. The model is implemented in the software packages M scATLAB and S scIMULINK, and is based on the wind-diesel test-bed at the Atlantic Wind Test Site (A scWTS) in PEI, Canada. Wherever possible, components of the model are validated with available measurements from the A scWTS system.; Three different frequency transducers (one phase detector and two frequency detectors) are modelled and incorporated into the design of a PID dump load frequency controller.; In this thesis, a static VAR compensator (SVC) is uniquely applied to the wind-diesel system to improve its voltage stability. With the SVC configured to compensate the reactive power of the wind turbine, the wind turbine disconnections yield similar responses as with the capacitor bank, but the flicker emissions due to wind turbulence are virtually eliminated. Adding a novel voltage control loop to the SVC reduces the voltage transients from the wind turbine disconnections to well within the specifications. In addition, the voltage stability of the entire system is improved. (Abstract shortened by UMI.)
