Cable thermal risk estimation for overplanted wind farms

Cable thermal risk estimation for overplanted wind farms
Cable thermal risk estimation for overplanted wind farms
This paper presents a methodology for the forward estimation of thermal risk in offshore wind farm cables under scenarios where the farm is overplanted for economic purposes. A dynamic thermal rating assessment of the cable is proposed to estimate the thermal effects of probable load current scenarios
considering actual temperatures. Calculated future temperatures are used to estimate the probability of the cable being overheated. Due to the ability of the method to estimate forward thermal risk, unnecessary power curtailment can be reduced while avoiding thermal damage to the cable. Simulated results of online thermal risk estimation and curtailment show additional power delivery of 7.26%, 9.16% and 9.67% per year for a 6% 9.9% and 13.7% wind farm overplanting respectively. The additional power is calculated compared to the annual power delivered (W h/year) with the use of the traditional continuous rating limits for the case studied.

Abstract

This paper presents a methodology for the forward estimation of thermal risk in offshore wind farm cables under scenarios where the farm is overplanted for economic purposes. A dynamic thermal rating assessment of the cable is proposed to estimate the thermal effects of probable load current scenarios
considering actual temperatures. Calculated future temperatures are used to estimate the probability of the cable being overheated. Due to the ability of the method to estimate forward thermal risk, unnecessary power curtailment can be reduced while avoiding thermal damage to the cable. Simulated results of online thermal risk estimation and curtailment show additional power delivery of 7.26%, 9.16% and 9.67% per year for a 6% 9.9% and 13.7% wind farm overplanting respectively. The additional power is calculated compared to the annual power delivered (W h/year) with the use of the traditional continuous rating limits for the case studied.
