ABB: Power Macau improve power supply reliability

    ABB and CEM history of cooperation for many years. In the process of cooperation, ABB's professional services and customized solutions for our customers has left a deep impression. Therefore, when CEM start ColoaneB station (CCB) generator circuit breakers (GCB) project, immediately thought of the ABB.

    CEM is a private power company,booster cables with the Macao Electricity franchise. It was built to meet the CCB Macau's growing power needs. The value of the 1,000 ten thousand patacas power system projects to improve power supply stability and reliability of CCB.

    Scope of work.

    According to the requirements of the project, ABB gas turbines and CCB in the existing installation of a transformer between the generator circuit breakers 12kV4000A level. ABB to help transform steam and 110kV substation protection program, including generator protection, AVR, 11kV synchronous, 110kV bus protection,battery clip 110kV and 110kV synchronization and steam turbine hardware interlocks between the substation and interlock tripping system.tow rope In addition, ABB also offers a generator known as CITECT control system. In addition to external equipment control system, ABB has also helped transform the existing power plant in the central remote control system, and participated in the generator circuit breakers steel design and construction of high-and the transformation of fire protection systems.


    Less than one month of down time and space constraints of existing plant is in the project by ABB the biggest challenge.ratchet tie dowm We will show this challenge into our value-added products, professional experience and opportunity management system. Within the time we succeeded in providing customers with the most efficient power generation system solutions, and minimizing the construction impact the normal operation of the customer.

    In addition, the project, we also face many other challenges, such as demolition of the existing isolated phase bus (IPB), and in order to ensure that the project completed on time, cooperation with third parties.

    Outstanding results.

    Design period, we anticipate the demolition of the existing risk of isolated phase bus. According to our risk assessment and quality control processes, we have developed contingency plans to address these issues. In order to control quality, we use special tools and operational procedures. In the choice of generator circuit breakers, we have chosen a grounding switch, CT and VT motor circuit breakers, reducing installation and commissioning time.

    As a general contractor for the project, ABB needs and civil engineering, mechanical, electrical contractors and plant operators to cooperate. Successful project management allows us to close with the cooperation of these contractors to ensure the project schedule. At the same time, our clear and effective communication between customers, to ensure that our customers can design a complete customized solutions.

    ABB (China) Co., Ltd. Tan, head of power systems of good management (DanielAssandri) said: "We are good local business capacity, and CEM trust in us, ABB and the CEM is to establish friendly and long-term relationship a key factor. We are very pleased to cooperate with the CEM, Macao meet the growing demand for electricity. "

    The transformer in the demolition of the old platform for the generator circuit breaker replacement 4.5m high steel high-profile, we also transformed the fire protection systems. After transformation of the protection devices, control systems and fire protection systems, central remote control system and synchronized with ABBsyn5301 be re-installed in the CCB panel 110kV power substation.
