东营经开区为解决海上风电装备测试成本高、周期长的问题,规划建设了国内首个临海风电装备测试认证创新基地。
19日,记者走进山东省东营经济技术开发区(下称“东营经开区”)看到,一排排巨大的白色风车迎风缓缓转动。在临海风电测试基地里,一场场严苛的风电机组性能测试正在有序开展。
风电机组进入市场前,需要经过一系列测试。此前,这些往往由企业自行到海上完成,成本高、周期长。如今,东营经开区建成全球规模最大、功能最全的临海风电测试认证基地,让企业在家门口就能拿“准入证”,大幅缩减企业测试成本。
在东营风电装备测试认证创新基地,中国东方电气集团有限公司自主研制的全球最大26兆瓦级海上风电机组,正在进行全工况数据检测认证。该机组年发电量达1亿度,能满足5.5万个家庭全年的用电需求。
“该基地能满足风电机组从部件到整机的一站式测试,可模拟海上机组实际运行的各种情况,验证机组的全面发电能力。”东方电气风电股份有限公司测试中心项目经理张恒告诉记者,各项数据检测达标后,企业就相当于拿到了风电机组进入市场的“准入证”。
但在过去,这张“准入证”并不好拿。企业往往要自行到海上建设测试机位及配套检测平台,时间和资金成本巨大。
2021年,山东省着手规划渤中、半岛北、半岛南三大海上风电装备制造产业基地,30多家上下游企业陆续落户东营经开区。随着产业的逐步壮大,专业测试平台短板却制约了新产品上市。为此,东营经开区成立工作专班,谋划打造国内首个临海风电装备测试认证创新基地。
“东营经开区的优势很明显,地势开阔、风速稳定、土地资源丰富,测试成本仅相当于大型海上试验风电场的四分之一。”东营市东汇产业发展集团有限公司招商一部主办黄艳霞说。
经过多轮实地勘测、方案论证,东营经开区最终决定在临海区域,规划布设12个大功率风电测试机位。
“我们的风电测试基地不同于商业风场,采用单机单线接入方式。当单台风机开展测试工作时,其余风机检测均不受影响。”东营东汇新能源科技有限公司运维管理部副部长于现勇解释说。但测试基地基础设计为30兆瓦级,在风机基础浇筑施工阶段,大体积混凝土一次性浇筑会产生热源,导致混凝土粉化,造成风机基础开裂及强度降低。
面对行业少见的技术难题,项目团队联合建设单位以及科研院所展开攻关。机位基础由专业团队研发设计,钢筋用量320吨,混凝土一次浇筑量3500立方米,相当于当前陆上风电基础的3倍。同时,团队通过循环通用冷却技术,精准控制风机基础内各部位混凝土温度,确保风机基础有效建成。
历时一年多建设,东营风电装备测试认证创新基地投入运行。国内多家头部风电企业的最新机型纷纷汇聚东营。从百米级叶片的极限载荷测试,到整机并网特性验证;从机电传动系统联合调试,到极端海况可靠性模拟,这里已成为行业公认的“技术考场”。
如今,8800亩的东营海上风电装备产业园内,37个总投资280亿元人民币的产业链项目,正形成集群式协同发展格局。一张“准入证”,延伸为整条产业链的“加速器”,正带动海上风电产业向深蓝加速奔跑。
The No. 2 boiler of Qinghai Huadian Golmud Phase I, the highest ultra-supercritical coal-fired power generation project in China, was successfully ignited on October 18, marking the unit entering the hot commissioning stage. This project is located in Golmud, Qinghai, with a total investment of approximately 6.2 billion yuan, and aims to improve the Qinghai power grid’s ability to absorb new energy.

The Economic Committee of the Legislative Yuan held a public hearing on state-owned energy industry budget allocations today. The business community called on the government to allocate losses to Taipower and PetroChina. Taipower expressed its gratitude and pointed out that the war between the United States and Iraq caused gas prices to rise sharply, absorbing costs of more than 70 billion yuan. It hopes that all walks of life will support the 71.1 billion yuan supplementary budget to improve finances and stabilize people's livelihood.

The Economic Committee of the Legislative Yuan held a public hearing on the losses of CNPC and Taipower and the revision of the Energy Management Act. The Kuomintang legislators proposed adding provisions for a loss-free withdrawal fund, and the General Accounting Office is worried that it will significantly weaken the energy fund's self-raised financial resources and affect business promotion.

National Tsing Hua University signed a cooperation agreement with NuCube Energy of the United States to evaluate the feasibility of introducing micro modular reactors (MMR) in Taiwan for research, application and deployment. Tsinghua University aims to set up one on campus as early as 2031, and hopes to use this to drive Taiwan's traditional industries to join the international nuclear energy supply chain.

China's Ministry of Commerce announced that it plans to include some solar manufacturing technologies in the export control list on the grounds that the relevant technologies involve sensitive fields of aerospace and national defense. This move is seen by analysts as an attempt to maintain China's monopoly in the photovoltaic field and may affect the overseas production plans of companies such as Tesla.

Regarding the progress and disbursement of the second phase of Taipower's offshore operations, the Ministry of Economic Affairs stated that the first batch of wind turbines has been installed and called on the contractor Fuwei to properly handle the joint loan dispute with the bank group. Taipower will make the completion of wind turbine installation and grid connection its primary goal.
