Xu Shuang Ankerui Electric Co., Ltd.    Jiading 201801 1 Overview According to statistics, China's total building energy consumption accounts for about 45% of the energy consumption of the social terminal, energy consumption accounts for about 8-15% of hotel turnover, and energy consumption accounts for 20.3% of global energy consumption. The hotel is a large consumer of electricity and water: A star-rated hotel with a building area of ​​8,000m2 to 10,000m2 will consume 1.3-1.8 million tons of standard coal a year, and its energy consumption is no less than a large factory. A 300-room hotel with a 1°C increase in air conditioning will solve the problem of power consumption for dozens of households; the average daily water consumption of a guest in a three-star or more hotel is 0.5-1.1 tons per day, and the current urban residents each The average monthly water consumption will generally not exceed 3 tons. The statistics of related data in 2011 show that there are more than 14,000 star hotel hotels in the country. As an energy consumer, saving energy and reducing basic consumption, on the one hand, it means reducing operating costs and increasing operating profit. On the other hand, it will actively promote and lead the realization of China's energy saving and emission reduction targets in the 12th Five-Year Plan period. 2 hotel meter configuration Technological innovation is the foundation of energy efficiency. Currently, most hotel companies still use artificial statistics to collect various energy consumption data. Business managers can only rely on statistical statements and billing bills such as electricity bills and water bills to understand monthly energy consumption. The operator controls the operation of the equipment based on experience and practice. The data of this extensive management method has poor timeliness and accuracy. Due to the lack of monitoring and analysis of the dynamic process of energy consumption, the energy consumption structure and operating mode cannot be detected in a timely manner. Problems that exist cannot be understood in a timely manner what parts of the energy consumed are reasonable and which parts are unreasonable. The energy energy management system automatically collects and monitors the distributed energy consumption data of the enterprise. The core of the system is a powerful set of energy efficiency management software. Through the statistics, comparison and analysis of various real-time and historical energy consumption data and trends, To help users identify and solve problems in energy consumption methods and structures, so as to targetly transform, adjust and optimize energy consumption processes and methods, and improve energy use efficiency Whenever the hotel's comfort, safety and economy depend on the reliability of the power distribution system! A safe and stable power supply and distribution system can ensure normal operation of various types of electrical facilities in hotels and the stable operation of intelligent systems, which effectively protects the hotel's comfort and safety environment, and at the same time contributes to the improvement of the hotel's profitability. How to ensure reliable and continuous power supply to hotels in air-conditioning, heating, ventilation, lighting and elevators, and how to improve power quality to ensure stable operation of all types of weak current systems and multimedia systems in hotels and how to control power in hotel operations? Loss and reduction of electricity bills are always the concerns of the hotel industry users. Therefore, a suitable electric energy meter is configured for the entrance circuit of the hotel power distribution system to perform comprehensive electric energy measurement and monitor the power quality of the system; the electric parameters of the power supply circuit such as the air conditioner and elevator are monitored in real time, and the electric energy usage is analyzed from multiple angles. To monitor the harmonic pollution of the power supply circuit of the multimedia communication equipment in the conference center; to comprehensively monitor the power supply circuits of the equipment room of each monitoring system and the system equipment of the front desk settlement center. Finally, using the background management software, the hotel is equipped with an automatic power management system to fully record the power consumption of various types of loads and analyze it in depth. According to the multi-angle load curve report, a reasonable power consumption model is established to save energy costs. Hotel industry power management system configuration scheme as shown below: 1) Power inlet APMD730 smart meters were deployed in the hotel's power supply line as management instruments for hotel properties. APMD730 intelligent instrument can detect three-phase current, voltage, active power, reactive power, power factor, apparent power, grid frequency, active energy, reactive energy, 2-31th order harmonics, total harmonic content, voltage Crest factor, telephone waveform factor, current K factor, voltage and current imbalance, peak voltage, voltage and current sequence, waveform tracking display, multi-rate energy statistics, maximum demand records, SOE event records. The APMD730 meter can be used to check the power quality of the power supply while ensuring the reliability of electricity consumption in the hotel, compared with the power meter installed on the side of the power company. There are numerous air-conditioning units in the hotel building, ventilation equipment and elevator equipment. The frequency conversion mechanism, control components and computer system equipment in the hotel are typical non-linear loads. The generated harmonics flow into the distribution system and pollute the power grid. The potential impact on reactive power compensation equipment will also affect the normal operation of various types of electrical equipment, reduce system efficiency, and increase the cost of electricity. According to the hotel industry's large number of non-linear loads, distributed dispersion, and large 3rd harmonic content, an active filter device ANAPF active power filter can be configured on the main busbar to perform overall harmonic control and completely eliminate the third harmonic. The resulting neutrality ensures the safety and reliability of the hotel's power supply system, guarantees the normal operation of various types of electromechanical equipment, improves the efficiency of power system management, improves system efficiency, reduces power consumption, prolongs equipment life, saves hotel electricity costs, and reduces operating costs. . The ANAPF active power filter is a new type of power electronic device for dynamically suppressing harmonics, compensating for reactive power, and balancing three-phase systems. It can compensate for varying harmonic currents and varying reactive power. Its application can be used. Overcoming the disadvantages of traditional harmonic suppression and reactive power compensation methods such as LC filters. 2) Primary load In the hotel industry, lighting, power, computers, telephones, electro-acoustic and video equipment, etc., in the main passages and important locations are classified as first-class loads. The majority of energy metering uses ACR network multi-function meters. ACR network multi-function instrument can provide comprehensive energy metering, can measure three-phase current, voltage, active power, reactive power, power, harmonics, etc., and provide comprehensive power monitoring for important power circuits. 3) Secondary load The air-conditioning system, general lighting and general power of the hotel are all secondary loads. Since the air-conditioning system of the hotel includes cooling and heating units, fans and pumps, and air-conditioning rooms, the electricity consumption accounts for a large proportion of the total electricity used by the hotel and needs to be used for this part. The power points are equipped with ACR network multi-function meters for comprehensive power monitoring. 4) Functional areas such as rooms and kitchens A single-phase or three-phase energy meter can be used in functional areas such as hotel rooms, cafes, sauna wellness areas, lobbies, kitchens, and public lighting areas to perform energy metering to facilitate comprehensive and detailed management of the overall energy consumption of the hotel. , timely feedback of energy consumption loopholes, assisting construction managers in discovering problems in the hotel energy use system, finding equipment or systems that consume too much energy or operating irrationally, and providing suggestions for improving energy-saving operation management; 3 hotel power management system functions 3.1 Real-time acquisition Since the “send, supply, change, match, and use†of electrical energy is completed at the same time, the use of electrical energy in electrical equipment is also changing with time.
