Abstract

Transmission of electrical power from the generator to the load is a very important part of the electric power system. In the transmission system, it is necessary to increase the voltage to minimize power losses. The transmission system commonly used is High Voltage Alternating Current (HVAC). However, in reality the HVAC system can cause large losses. There are other transmission systems besides HVAC, namely High Voltage Direct Current (HVDC). The purpose of this paper is to compare the performance of HVAC and HVDC transmission systems in distributing electricity to variations in transmission distance or conductor line length and transmission voltage variations. The performance of the HVDC and HVAC systems measured is the power losses in the line conductors. In addition, power losses in transformer 1, transformer 2, and active power in HVAC. In addition, power losses at station 1, station 2, and active power at HVDC. The type of power plant used in this paper is renewable energy. The renewable energy consists of photovoltaic and wind power plants. The results for very long transmission distances, HVDC has smaller power losses than HVAC. In addition, HVDC stations have higher power losses than HVAC transformers. Based on the total power losses, overall the total power losses in HVDC is smaller than the total power losses in HVAC.

HVAC和HVDC两种方式下可再生能源输出电力向负荷传输的比较

发电机向负荷的电力传输是电力系统的重要组成部分。在输电系统中，有必要提高电压，以尽量减少功率损耗。常用的输电系统是高压交流电(HVAC)。然而，在现实中，暖通空调系统会造成很大的损失。除了暖通空调，还有其他输电系统，即高压直流(HVDC)。本文的目的是比较HVAC和HVDC输电系统在输电距离或导体线路长度变化和输电电压变化时的配电性能。测量的HVDC和HVAC系统的性能是线路导体的功率损耗。另外，变压器1、变压器2和暖通空调有功功率的损耗。此外，站1、站2的功率损耗和高压直流有功功率。本文使用的发电厂类型为可再生能源。可再生能源包括光伏和风力发电厂。结果表明，在输电距离较长的情况下，HVDC的功率损耗比HVAC小。此外，HVDC站比HVAC变压器具有更高的功率损耗。从总功率损耗来看，总体上HVDC的总功率损耗小于HVAC的总功率损耗。
