Technical Field

[0001] The present application relates to the technical field of thermal power plants, and in particular to an intelligent energy management system for thermal power plants. Background Art

[0002] Thermal power plant is abbreviated as thermal power plant. Thermal power plant is a factory that uses combustibles as fuel to produce electricity. It is an important part of electricity production. Thermal power plant can be divided into coal-fired power plant, oil-fired power plant and gas-fired power plant according to the type of fuel.

[0003] In the related art, the basic production process of a thermal power plant is to heat liquid water to generate water vapor through the heat energy generated by the combustion of fuel, thereby converting the chemical energy of the fuel into thermal energy, and then using the pressure of the water vapor to drive the turbine to rotate, thereby converting the thermal energy into mechanical energy, and then the turbine drives the generator to rotate, and finally converts the mechanical energy into electrical energy. In the production process of a thermal power plant, in order to reduce costs, improve efficiency, reduce pollution, ensure safety, and meet policy requirements, it is necessary to manage the energy of the thermal power plant. At present, when performing energy management, the data such as coal consumption, power generation, power supply, and power consumption detection values ​​of the thermal power plant are generally collected by a data acquisition device preset in the thermal power plant, and then saved in the EXCFL table, and then the person in charge regularly processes the data, so as to timely discover and correct the unreasonable phenomena in the energy utilization of the thermal power plant.

[0088] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0089] reference Figure 1The embodiment of the present application discloses an intelligent energy management system for a thermal power plant, which includes an in-plant data collection device, an energy management analysis device, and an energy management control device. The in-plant data collection device is used to collect real-time energy data collection information in real time. The in-plant data collection device includes a power generation detection device, a coal consumption detection device, an in-field equipment power consumption detection device, a coal composition detection device, a combustion exhaust gas composition detection device, a steam emission image detection device, a liquid water initial input temperature detection device, and a weather condition detection device preset in the thermal power plant. The energy management analysis device is connected to the in-plant data collection device to receive the real-time energy data collection information. The energy management analysis device uses a pre-configured energy management analysis strategy to analyze and process the real-time energy data collection information and outputs the energy management control information at a first preset time interval according to the processing result. The energy management control device is connected to the energy management analysis device to receive energy management control information and generate energy management control constraints. The energy management control device includes a coal input adjustment device for adjusting the coal input, a combustion air input adjustment device for adjusting the combustion air input, and a liquid water input adjustment device for adjusting the liquid water input. The energy management control information is received by the energy management control device and the energy management control constraints are generated, so that energy management control is directly performed while detecting, thereby achieving the purpose of quickly and efficiently managing the energy of the thermal power plant. The specific method is as follows: the energy management device includes a monitoring model module, an association index module, and an Internet of Things configuration module. The monitoring model module is configured with a corresponding monitoring model information library corresponding to each energy generation device. The monitoring model information library stores a plurality of energy monitoring models. The energy monitoring model is indexed by energy management constraints. According to the monitoring model module, the corresponding energy monitoring model is retrieved according to the energy management constraints and configured in the energy generation device. The energy generation device has a deviation feedback unit. The deviation feedback unit obtains the operating status data of the energy generation device in real time, brings the operating status data into the energy monitoring model and generates corresponding operating abnormality characteristics. The association index module is used to configure the associated abnormality information in the corresponding energy generation device. The associated abnormality information includes a plurality of different associated abnormality data. Each associated abnormality data includes a trigger condition, an associated device address, and an associated execution instruction. When the obtained operating abnormality characteristic meets the trigger condition, the associated execution instruction is sent to the energy generation device corresponding to the associated device address. The energy generation device is configured with a short-distance communication unit. The short-distance communication unit is used to send the associated execution instruction. The Internet of Things configuration module is used to configure the device association address in the short-distance communication unit.First, a comprehensive analysis of the collected information is configured at preset intervals to determine the corresponding constraints, that is, the measures to be taken if an emergency occurs during this time period. Then, the corresponding energy monitoring model is called according to the constraints. The energy monitoring model uses the operating parameters of the power generation equipment as input variables. Different power generation equipment corresponds to different energy monitoring models, and different constraints have different energy monitoring models. The purpose of the energy monitoring model is to establish standards for abnormal situations. That is to say, for example, if the temperature value fed back by a sensor is too high, this feature exceeds the benchmark of the energy monitoring model, then it is identified as an abnormal feature. The present invention introduces a monitoring model instead of a corresponding numerical value because the monitoring may read a waveform for a period of time, and it may also be characterized as an abnormality by the interaction of several variable parameters. Therefore, it is more reliable to identify abnormal data through a model. Of course, the model can also be understood as a basis for judging normal and abnormal situations. On the other hand, corresponding to the use of short-distance communication of energy power generation equipment on site, other equipment can be adjusted according to preset associated execution instructions in abnormal situations to reduce system load or energy consumption and improve safety.

[0090] The energy management device also includes an instruction generation module, which generates control instructions according to energy management constraints and directly controls the operation of corresponding energy generation equipment. For macro adjustments, the corresponding control instructions can be adjusted directly after the identification is completed, such as increasing the damping of the fan or increasing the base power of the heat exchanger.
