Energy management system for fused salt energy storage combined with thermal power peak shaving

Abstract

The invention discloses an energy management system for fused salt energy storage combined with thermal power peak shaving. System software and hardware and system functions are included. Software andhardware of the system comprise a hardware platform, an operating system platform, a universal middleware layer, a unified support platform layer and an application software layer which are sequentially constructed from bottom to top, and system functions comprise data acquisition, processing, real-time data management, historical database management, man-machine interaction, report functions, operation monitoring and energy distribution of the energy storage system. The energy management system has the advantages that data acquisition and processing, valve control, fused salt maintenance management and man-machine interaction are achieved in fused salt energy storage combined with thermal power peak shaving, the management requirement of thermal power peak shaving is met, energy distribution and maintenance management of the fused salt energy storage system are achieved, normal operation of the fused salt system is guaranteed, and the peak shaving efficiency and safety are improved.

Description

Technical field [0001] The invention relates to an energy management system, in particular to an energy management system for molten salt energy storage combined with thermal power peak shaving, and belongs to the technical field of energy management. Background technique [0002] The distribution of power resources and regional economy in my country is unbalanced, the grid load fluctuates greatly, peak-shaving resources are scarce, the proportion of heating units increases, and the deep peak-shaving of thermal power units poses a risk to themselves and the safety of the power grid. With the intensive development of renewable energy, a series of problems have been brought to the power grid peak shaving and power grid operation regulation. At present, the construction of pumped-storage power stations in China is the main means to solve grid peak shaving and grid operation regulation. However, the location of pumped-storage power stations is affected by geographical location, water...

AI Technical Summary

Problems solved by technology

In order to adapt to changes in grid load demand, other peak-shaving units need to frequently lift and lower loads, and operate under special conditions for a long time, resulting in frequent swings of steam turbine valves, and boilers and other auxiliary equipment are subjected to severe temperature changes and alternating stress for a long time, seriously damaging equipment The service life not only leads to an increase in inspection frequency and maintenance cost, but also leads to an increase in the number of unplanned outages of the unit, which seriously threatens the personal safety of the unit, power grid and operators
