해상풍력발전단지 발전량의 보다 정확한 예측을 위해 발전단지 예정지 인근에서 측정된 풍속데이터가 반드시 필요하다. 풍속데이터 확보를 위해서는 해상기상탑을 설치하는 방법과 인근 해안가나 섬에 풍속계측타워를 설치하는 방법이 있다. 본 연구에서는 인근 섬에서 측정한 풍속데이터와 WAsP 방법을 이용하여 해상풍력발전단지의 발전량을 예측할 경우에 섬의 지형 및 지면조도의 변화에 따른 발전량 예측값의 민감도를 분석하여 섬의 형상의 불확실성이 발전량 예측에 미치는 영향을 정량적으로 파악하였다. 계측타워의 풍속측정 높이가 높아질수록 섬의 지형 모델링 오차가 발전량 예측에 미치는 영향이 작아졌으며, 섬의 지면조도 변화에 따른 발전량 변동은 미미한 것으로 나타났다.

Since Ross (1967), movement has been known to display what is called the island-sensitivity. As has long been advocated and assumed in the generative grammar, English DP and TP are the cyclic nodes/bounding nodes/barriers from which an extraction is disallowed, which turns into different versions of locality in the name of Phase Impenetrability Condition (PIC) in Chomsky (2000, 2001). With this technology, the bounding nodes enter into a new stage, Phases. In essence, however, Cyclicity, Subjacency, and PIC are all dealing with locality constraint on movement (Boecks 2012:58). While maintaining a theory-neutral stance between different versions of locality constraint on Wh-movement, the purpose of this paper is to highlight the two closely related constructions of English, Sentential Subject Construction (SSC) and its corresponding Extraposition Construction (EC) with respect to the island effect. The fact that Wh-constituent can be extracted neither from finite that-CP nor non-finite for-CP in SSC, while it freely moves out of both that-CP and for-CP in EC is analyzed with a null D head. As a consequence of this analysis, it is argued that a null D(P) is a necessary constituent in order to account for the impossibility of Wh-extraction from SSC. On the other hand, the ban on extraction is lifted in EC, due to the lack of the encapsulating DP.
