Description

201021357 IX. Description of the invention: [Technical field of invention] The power monitoring platform of the invention refers to calculating the load power by the m-shaped demand control gamma area method, and the average power consumption for the user terminal is lower than or equal to the contract capacity of the control center. . [Prior Art] According to, energy is the root of the ability to work, including coal gangue, oil and so on. Among them, the cleanest and most convenient energy source is no more electricity; our daily life depends on various energy sources such as lighting equipment, household electrical appliances, air conditioning equipment, etc., all of which use electric energy; in addition, gas stoves and The hot water is a gas system, and the transportation is the gas source of the stone source. It shows how important energy is. However, in the operation of various low-cost or large-scale waste houses, electricity is required, and the supply of electricity is an indispensable source of energy - because there are countless equipments operating in the plant, and some need 24 The hourly non-stop operation will increase the amount of electricity required. In addition, each processing company or large plant will sign an average power over-contract with the power company, and it will be used for the capacity of the average power every 15 minutes. If the _ capacity standard is exceeded, if the _ capacity is exceeded, the power consumption of the lion can exceed the standard. Then, the demand control method is used, and the slope of the demand increase is used to predict whether the contract capacity will be exceeded after 15 minutes, and the demand control mode It can be divided into a limited unloading and a slope-predicted unloading method. The method of limiting the unloading (as shown in Figure 亦) also sets the contract capacity Ai to be set to 'when the electricity usage demand E1 rises to the contract capacity Μ, then the electricity is used. The demand E1 is used to start the unloading down to the constant power, and the reverse unloading tiltable power α is controlled within the contract capacity A1, and the limited unloading mode can effectively control the electric power in the contract capacity. Within the scope of 201021357, but the average demand S1 for calculating electricity consumption cannot achieve the waste and loss of the contracted capacity A1 every 15 minutes, and the slope prediction domain (as shown in Figure 2) Method, the electricity usage demand. Take each rising-radian, that is, calculate the slope of one end of the arc from the end point p to the contract capacity, and then perform the appropriate unloading action, and then continue to do the lifting and unloading actions with the electric slope. The power consumption can be controlled within the contract capacity A2. The slope prediction unloading method uses the angle of inclination calculation to predict the power consumption of the next minute, and the electricity average demand is maintained within the contract capacity A2, and the slope prediction ❹ Although the unloading method can use the slope to calculate whether the average demand in the next minute will exceed the contract capacity, this method often has an error in the time synchronization. Even if the dynamic _ average is adopted, the contract capacity A2 cannot be completely guaranteed. The above existing demand control methods all set the average demand standard within the contract capacity. If the average demand reaches the contract capacity, the unloading action is immediately performed. Although 剌电#_ is within the contract capacity system, but there are often errors, and the average demand is not 100% full use of the contract capacity, resulting in waste and loss; and the traditional demand control platform system, in In the order of unloading and reloading of wounds, it is not free and more dynamic. In large-scale power users, there are a variety of equipment such as lighting, air conditioning, and business equipment. If the equipment is temporarily stopped or changed. The reason for the electric lining will be to change the order of unloading and reloading, although it is necessary to change the hardware line or equipment. Therefore, the inventors actively studied the power management control system and took the use of the consumer as a design consideration. The power monitoring platform system of the present invention has an independent control panel for each device, and the two independent modules are connected. To (4) the controller of the ship, through the hub can be monitored by the PC and monitored and managed by the remote Web Pan, and the power monitoring platform system can predict the demand of the energy and 6 201021357 unloading the phase of the power phase _ wire calculation In the case of sampling i5 minutes per second, for example, a total of _ seconds, which is based on the contract capacity, when the average time per second is more than about the contract time, the suppression time is less than or equal to the contract capacity tree clock time, and the area is calculated. The difference between the area of the suppression and the suppression is to be filled. Thus, the contracted capacity signed with the power company maintains the capacity of the average power in every second of every 15 minutes, and _ sign the contract (four) g_ to avoid unnecessary over-confidence. Invalid power costs incurred, as well as opportunities to further reduce the cost of electricity. ❹ [Summary of the Invention] The power monitoring platform system of the present invention provides a power management method for the user terminal, and the management step includes - step material a), setting and stopping the setting m (b) according to the scheduling, and operating the meter data (dynamic average sampling) - Step (c), demand forecasting and unloading, thereby controlling the average power consumption of the user's and using 100% of the contract capacity signed with the control center and the average of the user's average power consumption Can be less than or equal to the set contract capacity.
