本日敝研究室主任史蒂芬與研究員鄧宗文兩人拜訪高雄市政府中區污水處理廠新完成的小水力發電機組。

中區污水處理廠為高雄地區處理量最大的污水處理設施，其接收高雄市區約80%污水經淨化處理後排放至旗津外海。

其中最後的消毒池至放流站之間約有3.5公尺的落差，於2024年初步評估裝置容量可達140kW具有小水力發電效益。2026年初正式完成第一期兩部分別20kW與30kW的豎軸卡布蘭式水輪發電機安裝，所生產的電力供應廠內使用，首開臺灣第一座污水處理廠小水力發電之先例。

在當今農田灌溉、自來水、河川水力開發資源即將飽和的大環境下，污水處理小水力發電將會是小水力發電的全新領域。

Today, our research lab director, Štefan, and researcher, Eric, visited the newly completed small hydroelectric generator units at the Kaohsiung City Government's Central District Wastewater Treatment Plant.

The Central District Wastewater Treatment Plant is the largest wastewater treatment facility in Kaohsiung, receiving approximately 80% of the wastewater from Kaohsiung City before discharging it into the sea off Qijin Island.

The final disinfection tank has a hydraulic head of approximately 3.5 meters relative to the discharge station. A preliminary assessment in 2024 indicated that the plant's capacity could reach 140kW, enabling small hydroelectric power generation. The first phase, consisting of two vertical-shaft open-flume Kaplan turbine generators (20kW and 30kW), was officially completed in early 2026. The generated electricity will supply the plant's internal needs, marking the first time a wastewater treatment plant in Taiwan is utilizing small hydroelectric power generation.

Given the current saturation of agricultural irrigation, tap water, and river hydropower resources, wastewater treatment-based small hydropower will be a new area for small hydropower generation.

Our sincere thanks to the Taiwan Small Hydropower Green Energy Industry Alliance for the invitation to the Third General Meeting - Second Session (社團法人台灣小水力綠能產業聯盟第二屆第三次會員大會議) to present STHRL findings and design drawings of the powerhouses we had the chance to work on in the past few years.

Reposting an excellent example of the vortex rope captured during a laboratory test at the Federal University of Itajubá (UNIFEI), Brazil.

The very problem turbine manufacturers and operators are battling, especially when turbines such as Kaplan or Francis (reaction types) operate under partial-load or overload conditions. A "draft-tube surge" phenomenon, as it is sometimes referred to, leads to excessive vibrations transferred to turbine components, causing fatigue loads and eventually serious damage to the entire system.

There are already multiple solutions that can be applied based on individual scenarios. One solution is to pre-calculate the turbine operating boundaries—the hill chart—and operate the turbine only within these margins. Another is a set of modifications via a central runner cone that injects air or water, or a more passive solution—antiswirling fins. For smaller-scale systems, a less-bending, deeper water-coverage suction head might help.

Pumped Storage Hydropower Project Málinec-Látky.

A project based on the Government Resolution of the Slovak Republic

No. 799/2024 of 18.12.2024.

The intended final installed capacity is 2400 MW (as for installed capacity, the Slovak project challenges the largest European pumped storage facilities, such as 1800 MW at Grand'Maison and 1.5 GW at Cortes-La Muela).

The project implementation period is set for 2025-2035
The projected head is set for approx. 530 m.
Estimated budget: 1.8 billion EUR.

Prečerpávacia vodná elektráreň Málinec - Látky Prinášame Slovensku nový, ekologický zdroj elektriny – vodnú energiu, ktorá bude tichým, ale silným pomocníkom v energetickej budúcnosti krajiny.

• 本研究室成員2026年的第一場遺跡探勘。
• 臺灣海岸山脈東側歷史上第一座，也是截至2025年唯一一座水力發電廠。
• 1943年完成土木結構，卻從未擁有發電機組的發電廠。
• キナブカ発電所第四次現地探勘影像紀錄，即將推出。
--------------------------------------------------------------------------
• The Lab's first site exploration in 2026.
• Until now, it is the first and only hydroelectric power plant in history built on the eastern side of Taiwan's Coastal Mountain Range, also known as the Hai'an Range.
• A power plant with the civil engineering structures completed in 1943, but never had the gen-set installed.
• The 4th on-site exploration documentary of the Kinabuka Power Plant will be released soon.

2026開年第一趟遺跡探勘記錄
第四次キナブカ発電所調查

這次透過Garmin精確衛星定位，完成完整的後段水路航跡記錄。也嘗試從隧道南口潛入希望能找到北口，可惜北口疑似被土沙掩埋，爬進去隧道無法看到對面的光線，也感受不到風切聲。隧道中段比較開闊，但蝙蝠很多，擔心蝙蝠夾帶的傳染病病毒爆炸多，所以還是撤退回來放棄這段。

本次最大的發現，是從隧道南口回來前池，偶然在產業道路上找到第三次探勘沒找到的壓力鋼管錨座，去年三勘時，以前池遺跡直線向下扇形搜索毫無斬獲，蠻掃興的。這次四勘想到之前看過設計圖，水路跟鋼管應該是垂直轉角向下沖，所以往反方向下坡找，就偶然的找到了失聯已久的壓力鋼管錨座。

經初步整理與調查，現存錨座還有十個，每座錨座間隔約5公尺，長寬各約60公分，錨座頂僅簡單砌石作為鋼管固定架，其中第六錨座特別大，留有金屬吊耳，鋼管路往下到白手蓮生態農場內被水泥道路攔腰截斷，鋼管底接廠房處，確定已被剷平變成池塘，經精確定位測定落差約42公尺，符合日本酒井鐵工所的資料。

本次探勘雖然頭水路前段仍舊沒有找到，但最大的斬獲，除了找到鋼管錨座外，也確認已拆毀廠房的真正位置，キナブカ発電所調查應該到此就告一段落了，下一個目標預計是花蓮鳳林発電所二勘。
