Monitoring device for rapid load reduction of power plant set and method thereof

Abstract

The invention provides a monitoring device for rapid load reduction of a power plant set. The monitoring device of rapid load reduction of the power plant set is characterized in that a DCS of a generator set is in electric connection with a USB interface of a monitoring computer, a thermoelectric couple arranged at the outlet of a generator set high-voltage bypass is in electric connection with a temperature measurement resistor, the temperature measurement resistor is in electric connection with a data collector, a pressure transmitter electrically connected with the generator set and a differential pressure transmitter electrically connected with the generator set are electrically connected with a voltage-measuring resistor, the voltage-measuring resistor is electrically connected with the data collector, the data collector and the thermoelectric couple installed on a boiler drum and electrically connected with the boiler drum are in electric connection with the temperature measurement resistor, the temperature-measuring resistor is in electric connection with the data collector, and the data collector is in electric connection with the USB interface of the computer. The supervisor information system computer of the generator set is in electric connection with an FCB historical data computer, the FCB historical data computer is in electric connection with the FCB monitoring computer through a network interface of the FCB monitoring computer, and provides the method for the FCB monitoring computer. The monitoring device for rapid load reduction of the power plant set can ensure that the FCB process is safe and reliable, enhance the risk-resisting capability and enable a power grid to be operated safely and stably, and the method is scientific, reasonable and effective.

Description

technical field [0001] The invention relates to the field of measurement, and relates to a monitoring device and method for rapid load reduction of power plant units. Background technique [0002] Unit fast load reduction, that is, FCB, Fast Cut Back, its abbreviation is FCB, refers to when the unit is running higher than a certain load setting value, due to internal or external power grid failure and disconnection from the power grid, all external power supply loads are instantly thrown off , but in the absence of boiler MFT, it is used to maintain the automatic control function of decommissioning of the generator with substation power or shutdown without stopping the boiler. [0003] Some developed countries and regions, including the United States and Canada, Moscow in Russia, London in the United Kingdom, Italy in western Europe, France and Germany, have successively experienced grid failures and serious accidents that led to large-scale power outages, causing social lif...

Problems solved by technology

[0004] For regional or urban power grids dominated by coal power without hydropower support, in the event of a system breakdown, the restart of coal power units requires a considerable amount of plant power, and the recovery time is long, so the impact on society will be more serious
