Abstract

The invention discloses a monitoring system for an energy storing device for output power of a smooth wind power system, and in particular relates to a monitoring system for a battery energy storing device for output power of a smooth wind power system. The energy storing device and an output line of the wind power system are connected in parallel on an alternating current bus; the monitoring system comprises a main server and a sub server; the main server comprises a monitoring host machine, an operation machine, a maintenance machine, a station master machine and a training machine which are connected to a maintenance information bus; and the sub server comprises a current converter monitor, a fan monitor, a power grid monitor and an auxiliary equipment monitor. The monitoring system coordinated with the energy storing device for adjusting the wind power generation output power effectively reduces the impact and influence of wind power synchronization to the power grid, improves the consistency of the wind-power output power and prediction, ensures the confidence level of power supply, and improves the capability of the power system for receiving the wind power.

Description

technical field [0001] The invention relates to a power management system, in particular to a monitoring system of a battery power storage device for smoothing the output power of wind power generation. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts. In recent years, China's grid-connected wind power has developed rapidly. Due to the randomness and intermittent nature of wind energy, the output of wind turbines fluctuates frequently, and the reliability of wind farm output is also poor. If the proportion of wind power is too large, the pressure on frequency regulation and peak regulation of the power grid will increase, and the long-distance power transmission of the power grid will increase. The technical requirements and operating costs of el...
