“…• Beban Mati Merupakan parameter yang digunakan sebagai beban tower itu sendiri yang berupa beban konstruksi serta material pendukungnya [13]. Dapat diklasifikasikan menjadi tiga bagian [14], yaitu Vertical Load (beban struktur pendukung, beban konduktor, fitting, insulator dan aksesorisnya); Horizontal Transverse Load (beban tekanan angin ke struktur tower dan struktur pendukung); dan Horizontal Longitudinal Load (beban tekanan angin secara melintang).…”

Pengoperasian jalur transmisi SUTT 150 kV Kenten – Tanjung Api-Api menjadi krusial karena merupakan jalur penyaluran energi listrik utama atau backbone sistem 150 kV Sumatera – Bangka. Selama masa operasi, diketahui telah terjadi tiga kali gangguan yang mengakibatkan tower roboh, sehingga mengganggu keandalan penyaluran energi listrik dari Pulau Sumatera ke Pulau Bangka. Penelitian fokus pada investigasi terhadap penyebab tower roboh yang terjadi pada tanggal 11 November 2023. Investigasi dan penelitian dilakukan dengan metode pengumpulan data primer secara visual, identifikasi kelengkapan material tower, interview saksi mata, pengambilan sampel data cuaca dan pengambilan data histori fault recorder di gardu induk. Hasil penelitian diharapkan dapat menjadi referensi perbaikan berkelanjutan terhadap proses konstruksi dan pengoperasian jalur transmisi dalam rangka menjaga keandalan dan kualitas penyaluran energi listrik ke pelanggan dan masyarakat sekitar.

“…Other significant ice storms that affected power systems in recent decades include the 1990 Iowa storm, which damaged several power transmission structures [7], the 1998 ice storm in southern Quebec and northern New York, and the 2013 North American ice storm that also affected Canada and Northeastern United States (US) and caused extended outages and significant economic losses [8]. In particular, the 1998 ice storm in Canada caused about $3 billion in damage and left millions of customers without power -some for TABLE 2.…”

Enhancing Power Grid Resilience Against Ice Storms: State-of-the-Art, Challenges, Needs, and Opportunities

et al. 2023

Ice storms have significantly impacted power systems in many ways over the past decades, causing serious damage to power generation, transmission, and distribution assets. Such storms have led to massive and extended power blackouts that have disrupted the lives of many communities, thus raising concerns from several electricity sector stakeholders. This paper aims to provide power grid operators, engineers, researchers, and regulators a comprehensive overview and comparison of the existing short-and long-term planning and operational methods to enhance the resilience of power grids against ice storms. Moreover, the paper also discusses several challenges, needs, and opportunities for future research and development, with a special focus on planning and operation mechanisms for power transmission and distribution network operators.

“…For example, the response of stranded cables to exciting forces produced by wind is studied and details of an analytical and experimental study of self‐damping cable are presented in [1]; cables with different characteristics are simulated and tested at transverse wind incidence, the results of which confirm the importance of turbulence in the dynamic response and demonstrate that the aerodynamic damping plays an important role in the dynamic behaviour of the cables [2]. Gupta et al [3] quantify potential load leading to different failure possibilities during an ice storm; Jianwei and Lilien [4] put forward a full multi‐span iced transmission line model with three degrees of freedom, which is applicable for describing the galloping phenomena of both single and bundled lines and so on. A rational analytical method for determining dynamic response of wind‐excited large truss towers installed with friction dampers is presented and the effectiveness of friction dampers is investigated in [5]; extreme wind statistics are used to evaluate the clearance requirements in order to perform a specific tower design in [6].…”
