A method of using real-time power to automatically accumulate over and under power in power plants

Abstract

Disclosed is an automatic power-plant exceeded and lacked electricity quantity accumulation method through use of real-time power. The method relates to an electrical power system exceeded and lacked electricity quantity accumulation method and solves the problems that electricity meters are not capable of storing planned values and real-time exceeded and lacked electricity quantity cannot be accumulated. The method is as follows: acquiring real-time to-be-inspected data which meet a precision demand through an energy management system (EMS); under a condition that secondary system security protection is guaranteed, realizing unidirectional transmission of planned value information from an application security subarea IV to a real-time security subarea I and developing a special-purpose management and transmission program through use of an FTP service and EXCEL; carrying out up / down float calculations of a power plan curve as required to form top and bottom plan curves; calculating electricity quantity according to a time integral principle through use of an equation that electricity quantity equals instantaneous power; and comparing the difference between a real-time power electricity and top and bottom limitation of a planned inspection in a real-time manner and calculating the electricity quantity through integral of the exceeded and lacked electricity. The automatic power-plant exceeded and lacked electricity accumulation method through use of the real-time power quantizes assessment indicators so that facilitates monitoring and controlling of the power plant.

Description

technical field [0001] The invention relates to a method for accumulating excess and shortage electricity in a power system, in particular to a method for automatically accumulating excess and shortage electricity in a power plant by using real-time power. Background technique [0002] At present, the construction of power sources in most parts of the country is seriously ahead of the construction of power grids, causing large units in the province to shut down or fail to run at full capacity, and the operation is extremely uneconomical. At the same time, due to reasons such as heat supply, local power plants continue to generate electricity online, and the assessment methods for local power plants are relatively backward, resulting in uneconomical operation of the entire network and a decline in peak-shaving capabilities. For each power plant, in terms of electricity assessment, the watt-hour meter cannot accurately reflect the amount of electricity generated by the daily u...
