据11月26日Energy Global报道,ABB集团赢得了一份价值250万美元的合同,升级科佩(Copel)电力公司的Governador JoséRicha水电站。
ABB集团将为位于伊瓜苏河上有20年历史的Governador JoséRicha水电站的四台发电机组提供励磁系统和调速系统,并帮助科佩公司利用预测诊断提高其运行数据的可视性。该水电站的额定发电量为1240兆瓦,有能力满足约450万居民的用电需求(相当于巴拉那40%的人口)。
ABB巴西公司工业自动化主管Mauricio Cunha表示:“励磁系统和涡轮调速器的升级,以及与ABB Ability?800xA自动化系统的集成将提高这座水力发电厂的性能和可靠性。”
ABB的Unitrol?6000静态励磁系统包括一个高性能控制器。现代化的硬件使得Unitrol?6000控制回路能够不断开与电网的连接,就对电网干扰做出更快的反应。该系统也有两个单独的通道和一个额外的备用通道,用于发电机的紧急控制。每个通道的设计都是为了处理最大的场电流,提高可靠性。
在系统仍在运行的情况下,“热插拔”的维护将改善核电站的可用性,并延长发电机的正常运行时间。延长正常运行时间可以提高盈利能力,同时也保护了电子元件。
科佩公司是巴西电力行业最大的公司之一。它拥有46座的发电厂,其中有20座水力发电厂,1座热能发电厂和25座风力发电厂,并运营着一定数量的水力发电厂。科佩电力公司在其它11个发电项目中拥有权益,总额定生产能力为6394兆瓦。ABB还为科佩提供资产管理和优化工厂生命周期服务。
新系统包括一个转速涡轮调节器,并符合电网规范。

ABB wins contract to upgrade Copel hydroelectric power plant in Brazil
ABB has won a US$2.5 million contract to upgrade Copel’s Governador José Richa hydroelectric power plant.
ABB will provide excitation systems and speed regulation for four generator units at the 20-year-old Governador José Richa hydroelectric power plant on the Iguazu River, and help Copel (Companhia Paranaense de Energia) enhance visibility of its operational data using predictive diagnostics. The hydroelectric power plant produces 1240 MW of installed power, with capacity to meet the power demands of approximately 4.5 million residents, or 40% of Paraná’s population.
“The upgrade of the excitation system and the turbine speed regulators and their integration into the ABB Ability? 800xA automation system will improve the performance and reliability of this hydroelectric power plant,” said Maurício Cunha, Head of Industrial Automation, ABB Brazil.
ABB’s Unitrol? 6000 Static Excitation System (SES) includes a high-performance controller. Modern hardware allows the Unitrol? 6000 control loop to react faster to grid disturbances, without disconnecting the unit from the grid. The Unitrol? 6000 SES also has two separate channels and an additional backup channel for emergency control of the generator. Each channel is designed to handle the maximum field current, enhancing reliability.
‘Hot swap’ maintenance, while the system is still in operation, will improve availability and extend uptime for the generator at the plant. Extending uptime increases profitability, while also safeguarding the electrical components.
Copel is one of the largest companies in the Brazilian electricity sector. It has 46 of its own power plants - 20 hydroelectric, one thermal and 25 wind farms – and operates a quota of hydroelectric power plants. Copel has interests in 11 other generation projects, totalling an installed capacity of 6394 MW. ABB is also supporting Copel with asset management and life cycle services to optimise the plant.
The new system includes a speed turbine regulator and complies with grid code compliance regulations.
