Description
技术领域technical field
本发明涉及一种电力系统的变电站计量数据异常报警方法。The invention relates to a method for alarming abnormal metering data of a substation in a power system.
背景技术Background technique
变电站计量数据反映变电站用电总量及站内各用电线路负荷侧的用电量，是站内用电计费的重要依据，必须确保计量数据准确可靠。Substation metering data reflects the total power consumption of the substation and the load side power consumption of each power line in the station. It is an important basis for electricity billing in the station. It is necessary to ensure that the metering data is accurate and reliable.
在以往的变电站中，采用计量装置采集各等级电压互感器的电压和各用电线路的电流的相量，通过电量采集装置计算得出各用电线路功率，作为计费主要依据。In the previous substation, the metering device was used to collect the voltage of each level of voltage transformer and the phasor of the current of each power line, and the power of each power line was calculated by the power collection device as the main basis for billing.
现有的计量装置没有完善的报警功能，当出现采集电压缺相、采集电压与采集电流反向序、采集电流其中两相反相或采集电压某两相反相的情况时会出现计量数据大幅度异常的情况，如果在变电站投运后，由人为或设备原因造成上述情况，无法及时发现，会造成计量数据丢失，用电计费小于实际用电量的严重后果，给供电公司造成极大损失。此类情况下，当前的计量表计及电量采集装置均无报警功能。The existing metering device does not have a perfect alarm function. When there is a phase loss of the collected voltage, a reverse sequence between the collected voltage and the collected current, two of the collected currents are in opposite phases, or a certain two of the collected voltages are in opposite phases, the metering data will be greatly abnormal. In some cases, after the substation is put into operation, if the above situation is caused by human or equipment reasons and cannot be discovered in time, it will cause the loss of metering data, and the serious consequences of electricity billing being less than the actual electricity consumption will cause great losses to the power supply company. In this type of situation, the current meters and power acquisition devices have no alarm function.

步骤9、当Pb不等于0时，判断Pc是否等于0，如Pc不等于0则进行下一条线路的巡检，如Pc等于0则判断Pa是否大于0并分别进行步骤9.1和步骤9.2；Step 9, when Pb is not equal to 0, judge whether Pc is equal to 0, if Pc is not equal to 0, then carry out the patrol inspection of the next line, if Pc is equal to 0, then judge whether Pa is greater than 0 and perform steps 9.1 and 9.2 respectively;
步骤9.1、当Pa大于0时则由电量采集装置通过通讯设备向远方供电调度中心和用户变电站发出计量数据异常报警，提示A相和C相电压反相，并在5分钟后利用与电量采集装置连接的测控装置跳开用户变电站内出现计量数据异常的线路；Step 9.1. When Pa is greater than 0, the power collection device will send an alarm of abnormal metering data to the remote power supply dispatching center and user substation through the communication equipment, prompting that the phase A and C phase voltages are reversed, and use the electricity collection device after 5 minutes The connected measurement and control device jumps off the line with abnormal metering data in the user substation;
步骤9.2、当Pc小于0时则由电量采集装置通过通讯设备向远方供电调度中心和用户变电站发出计量数据异常报警，提示C相电压断路，并在5分钟后利用与电量采集装置连接的测控装置跳开用户变电站内出现计量数据异常的线路。Step 9.2. When Pc is less than 0, the power collection device sends an alarm for abnormal metering data to the remote power supply dispatching center and user substation through communication equipment, prompting that the voltage of phase C is open, and uses the measurement and control device connected to the power collection device after 5 minutes Jump away the line with abnormal metering data in the user substation.
