| 摘 要： | 谐波不仅影响电力设备的安全运行,还影响电能表的计量精度.针对电子式电能表在电网存在谐波的情况下计量存在的不合理性,提出了一种合理的计量方案.通过建立三角波时分割模拟乘法器仿真模型,运用电力电子仿真软件PSIM,对方案进行了仿真验证.仿真结果表明了方案的有效性.

| Abstract: | Harmonic not only affects the safety running of electric equipment,but also affects electrical energy meters precise.Aming at the power measurement is not accurate when there is harmonic in the power system,a reasonable measurement scheme was brought out.The triangle-comparing PWM model based on PSIM was established and the scheme by simulation was certified.The results proved the effectiveness of the scheme. |
