Problems solved by technology

The scheduling process data of the above-mentioned prior patent applications all come from physical data, and the delay simulation of the scheduling process cannot be performed. The scheduling period is a fixed value, and the scheduling decision simulation cannot be performed, and it does not have long-term, non-fixed time scheduling effects.
Thermal power plants are relatively typical energy-consuming enterprises in the process industry. The power consumption also has certain rules with the periodic changes of the seasons. The production process not only requires long-term scheduling, but also needs to divide medium and long-term scheduling into more detailed ones. In the operable time period, there are deficiencies in the application of existing technology scheduling systems and methods, which affect the efficiency of enterprises

Abstract

The invention discloses a dispatching method and a dispatching system based on load online forecasting of a thermoelectric power system. The dispatching method has the main objects of a boiler and a vapor generating set which are the core equipment of a thermoelectric power generation system. The dispatching process comprises the following steps: a. acquiring data; b. creating a real-time database and a historical database; c. analyzing data and making a dispatching decision, creating a decision dispatching knowledge base to obtain a corresponding operation decision in the current optimal state to be reached and in the recent optimal dispatching state, comparing the expectation effect of the dispatching decision with an actual effect, taking the result as the condition of load forecasting, and finally obtaining the optimal dispatching decision through human-computer interaction. The dispatching system comprises a field data acquiring terminal, a field production layer DCS, a management layer ERP, a center data server and a manufacture execution and management layer MES. The invention overcomes the defects existing in the prior art; and based on the production capacity and the distribution forecast of a thermoelectric plant, the dispatching method and the dispatching system facilitate improving the production operation efficiency of enterprises, lowering the source consumption and reducing the pollution discharge.
