As an industry leader in the field of building energy conservation and automation, Hongyan Electric is also clear in solving the energy efficiency challenges brought about by harmonic management in the medical industry. Through the unique “integration of reactive power compensation and pulse current management” solution for the engineering and construction market, the seamless splicing and integration of the engineering and building intelligent management system and the power management system will greatly improve the hospital’s energy consumption and power engineering operations Carry out the integrated management method of “supervision, management and operation”. Among them, the intelligent power distribution system, as the core of the overall solution, integrates intelligent hardware, customized software and technical professional services, forming a technology that uses intelligent hardware to collect accurate measurement information, uses customized software for statistical analysis, and provides technology Closed-loop control system software for professional project life cycle service projects. Based on the underlying equipment interconnection technology and three-tier system architecture of the Ethernet interface, it maintains the comprehensive management of energy consumption level, power quality, electrical equipment property and operation and maintenance management of medical equipment industry users, and improves the overall operational efficiency.
Due to the diversity of hospital outpatient work, there are many characteristics, such as dense staff, large number of abortions, and patients’ medical life cannot be strictly distinguished. Construction equipment, construction medical equipment, and ward medical equipment are all dense. The hospital outpatient power supply system has a high load level, and the power supply and distribution method is quite different from other industrial buildings. There are many kinds of power experiment instruments, but customers lack power expertise. There are many safety risks in power engineering consumption. Power supply and distribution problems such as leakage currents and sudden power outages pose huge potential risks to patients.
Combined with the commercial power supply design and load level of the power distribution system design, the division of medical places and facilities, and the time requirements for automatic power supply restoration, after contacting the local power supply department, the project adopts two-way 10kV cables, embedded cables, two-way power supply and standby at the same time.
All kinds of precision medical equipment in the medical industry such as CT, X-ray machines, nuclear magnetic resonance machines and other medical equipment, a large number of elevator equipment, air conditioners, computers, UPS, variable frequency pump yarn systems, etc. not only show the increase of high-order harmonics, but also the change of load characteristic. In the past, hospitals generally used capacitor banks with fixed capacitance compensation or AC contactor switches. However, in a pulse current environment, such traditional compensation devices cannot meet the compensation requirements, and traditional capacitor compensation devices will increase the pulse current, thereby affecting the safety of the compensation device itself.
User Value of Reactive Power Compensation and Harmonic Control
Reduce the harm of harmonics, prevent the working voltage caused by harmonics from increasing and destroying common faults such as precision instruments, and improve the safety factor of the power supply system.
Govern harmonics, reduce harmonic current injected into the system, and meet our company’s standard requirements;
The reactive power dynamic compensation reduces the system power supply current and improves the power factor.
Problems you may encounter?
1. There are many single-phase loads, and single-phase loads can cause zero-phase harmonics, which can cause problems such as three-phase imbalance and three-phase asymmetry
2. The non-linear load ratio is high, and the harmonic distortion rate of the harmonic source is large;
3. Many intelligent and automated equipment in building power distribution have high requirements on power supply quality, especially sensitive to harmonics.
Our solution:
1. Use the reactive power of the compensation system of the company’s static safety compensation device, and rationally configure the reactance rate according to the harmonic conditions of the system to prevent harmonic amplification
2. The static safety compensation device Hongyan TBB adopts a mixed compensation method of three-phase common compensation and partial compensation to meet the compensation requirements of the three-phase unbalance of the system;
3. According to the mixed application of Hongyan active filter and harmonic protector HY1000, it can deal with the pulse current hazard of the power distribution system of municipal engineering buildings, reduce the loss of system software, and optimize the high-efficiency operation of the power distribution system. Customers with high requirements for power safety production.
